TECHNICAL FIELD

The present disclosure relates to an air suction pump and a method of vacuum sealing vinyl bag using same, and more particularly, to an air suction pump and a method of vacuum sealing vinyl bag using same, which manually discharge the internal air of a vinyl bag to the outside to apply vacuum into the vinyl bag and immediately seal the vinyl bag.

BACKGROUND ART

In keeping food such as fruit, vegetable, meat, and side dish, the food can quickly be decomposed or go bad due to oxygen in air when the food is exposed to the air.

To solve this problem, vacuum vessels that discharge the internal air thereof to the outside to keep food in a vacuum state are used.

The vacuum vessel may include a discharge means for discharging the internal air of the vacuum vessel to the outside, but, generally, the vacuum vessel includes a check valve, disposed at one end of the vacuum vessel, for discharging the internal air of the vacuum vessel to the outside, and discharges the internal air of the vacuum vessel to the outside using a separate automatic pump or manual pump.

Since automatic pumps are expensive, manual pumps are much used generally.

General manual pumps include a housing, a piston part disposed inside the housing, a load member that is coupled to the piston part at one end of the load member and exposed to the outside of the housing at the other end of the load member, and a handle part coupled to the other end of the load member.

Since the related art manual pump simply has a vacuum suction function, the function of the related art manual pump is simple, and moreover, when intending to seal a vinyl bag, the related art manual pump needs to include a separate sealing apparatus.

Advantageous Effects

According to the above-described air suction pump and method of vacuum sealing vinyl bag using same, the following effects are achieved.

The present invention simultaneously performs the air suction function of a manual pump and a sealing function of sealing a vinyl bag by using one product, thus achieving a multipurpose effect with one apparatus.

Particularly, the present invention sucks the internal air of a vinyl bag having no check valve and immediately heat-sutures the vinyl bag, and thus can be applied to general vinyl bags having no check valve.

Moreover, the receiving part receives a foreign material discharged from a vinyl bag, thus preventing pollution due to the foreign material moved to inside the housing.

Moreover, the present invention cuts a vinyl bag having no check valve by using a punch projection, sucks the internal air of the vinyl bag, and immediately heat-sutures the vinyl bag. Accordingly, the present invention can be applied to general vinyl bags having no check valve.

Moreover, the present invention discharges the internal air of a vinyl bag to the outside without cutting the vinyl bag by using only the air suction pump having a size less than that of the opening of the vinyl bag, and heat-sutures the vinyl bag to apply vacuum into the vinyl bag, thus providing convenience in managing and carrying.

Moreover, the compression amount of the main gasket is adjusted by a stopper when the housing descends, and thus, when a vinyl bag is much pressed by the main gasket, the present invention enables the internal air of the vinyl bag to penetrate a portion pressed by the main gasket.

That is, when the main gasket presses a vinyl bag too hard, the internal air of the vinyl bag cannot penetrate the presses portion, and thus, it becomes difficult to apply vacuum into the inside of the vinyl bag. According to the present invention, however, due to the stopper, the main gasket appropriately presses a vinyl bag, and thus, the internal air of the vinyl bag is discharged to the outside through the pressed portion.

Moreover, a first heating wire is heated by a button part disposed between the housing body and the handle part, and thus, when the button part descends maximally, the first heating wire is heated, thereby preventing power from being unnecessarily applied to the first heating when the piston member ascends and descends.

Moreover, by manually reciprocating the piston member, the present invention easily applies vacuum into a vinyl bag, and simultaneously, when the application of vacuum is completed, the present invention heat-sutures the vinyl bag to seal the vinyl bag.

Moreover, the second communication hole is formed in the lower portion of the base member, thus enabling the application of vacuum into a vacuum vessel as well as a vinyl bag, and enabling the separation of a cork from a wine bottle.

Moreover, a press part for pressing the top of the check valve is provided, and thus, the check valve can better seal the top of the suction hole.

Moreover, a rail projection is provided, and thus, a zipper part of zipper bag can better be clamped.

MODE FOR INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

First Embodiment

FIG. 1 is a perspective view illustrating an air suction pump according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view illustrating the air suction pump according to the first embodiment of the present invention. FIG. 3 is a sectional view illustrating the air suction pump according to the first embodiment of the present invention. FIG. 4 is a perspective view illustrating a coupling member and an ascending/descending member according to the first embodiment of the present invention.

As illustrated in FIGS. 1 to 4, the air suction pump of the present invention includes a base member 110, a housing 120, a piston member 130, a first heating wire 140, and a power supply part 150.

The base member 110 is a part that is supported by a bottom. A position display part I may be formed at the center of a top of the base member 110 such that the below-described discharge hole 175 of a vinyl bag 170 is disposed at an accurate position.

Furthermore, a ring shape of first pressurization projection 113 and a ring shape of first packing member 112 surrounding the first pressurization projection 113 are mounted on the top of the base member 110.

Moreover, a guide projection 115 is formed to protrude in a vertical direction, at a side surface of the base member 110.

The housing 120 is mounted on the base member 110 to be movable in the vertical direction. A top and a bottom of the housing 120 are opened.

A ring shape of second packing member 122 corresponding to the first packing member 112 is mounted on the bottom of the housing 120.

A guide part 125, into which the guide projection 115 is inserted and slides, is formed at the housing 120.

The guide part 125 is opened in a downward direction such that the guide projection 115 is inserted into the guide part 125 in a below direction.

Furthermore, a first spring 116 is mounted on a top of the guide projection 115, and elastic-supports the base member 110 and the housing 120 in a direction deviating from each other.

That is, the first spring 116 is mounted on the guide projection 115 and on an inner side surface of the guide part 125, and a bottom of the housing 120 is separated from a top of the base member 110 in the vertical direction in a free state.

A catching projection is formed at an upper end of the guide projection 115, and a catching jaw, by which the catching projection is caught, is formed at an inner side surface of the guide part 125. Therefore, the guide projection 125 is inserted into the guide part 125, and prevents the housing 120 and the base member 110 from being arbitrarily decoupled from each other.

The piston member 130 is disposed inside the housing 120, and an upper portion of the piston member 130 passes through the top of the housing 120 and is exposed to the outside. A handle part 138 is formed on the piston member 130.

A separate sealing apparatus 160, as illustrated in FIGS. 1 to 3, may be mounted on the piston member 130, and may heat-seal an opening of the vinyl bag 170.

In this case, the sealing apparatus 160 includes a cover member 161 that ascends or descends through the handle part 138, and a sealing heating wire 162 that is disposed under the cover member 161 and exposed to the outside when the cover member 161 descends.

The sealing heating wire 162 may be connected to the power supply part 150. When necessary, the sealing heating wire 162 may be heated by the power supply part 150.

The sealing apparatus 160 may be mounted in various structures, in addition to the illustrated of FIGS. 1 to 3.

The first heating wire 140 is formed in a closed curve shape, and mounted to be exposed in a lower direction of the piston member 130.

In the present embodiment, the first heating wire 140 is formed in a ring shape.

In this case, the first heating wire 140 is disposed inside the first packing member 112 and the second packing member 122.

Furthermore, the first heating wire 140 is mounted with respect to the position display part I formed at the base member 110.

Unlike the present embodiment, the first heating wire 140 may be mounted on a bottom of the housing 120 to be exposed to the outside.

The power supply part 150 supplies power to the first heating wire 140. In the present embodiment, the power supply part 150 is built in the piston member 130.

The power supply part 150 supplies the first heating wire 140 and the sealing apparatus 160 mounted on the piston member 130.

A supporting part 131, on which a fixing terminal 136 connected to the power supply part 150 is mounted, is formed inside the piston member 130.

Furthermore, an ascending/descending member 132 is mounted under the piston member 130 to be movable in the vertical direction.

The ascending/descending member 132 protrudes in a downward direction further than the bottom of the piston member 130. The ring shape of first heating wire 140 is mounted under the ascending/descending member 132 to be exposed in a downward direction.

In this case, the diameter of the first heating wire 140 is equal to that of the first pressurization projection 113, and thus, the first heating wire 140 may contact the first pressurization projection 113 when the piston member 130 descends.

A coupling member 133, which is disposed inside the first heating wire 140 and fixing-coupled to the supporting part 131 with a screw, is disposed under the ascending/descending member 132.

To this end, a concave groove is formed in the center portion of the ascending/descending member 132, and the coupling member 133 is disposed in the concave groove.

Furthermore, the first heating wire 140 is mounted on a bottom of an outer circumference surface of the ascending/descending member 132, around the coupling member 133.

A second spring 135, which elastic-supports the ascending/descending member 132 in the coupling member 133 direction, is disposed between the supporting part 131 and the ascending/descending member 132.

Moreover, a connection terminal 146, which passes through the ascending/descending member 132 and is extended in the fixing terminal 136, is formed at the first heating wire 140.

Therefore, in a free state, the fixing terminal 136 and the connection terminal 146 are separated from each other by the elastic force of the second spring 135, and, when the ascending/descending member 132 moves in the vertical direction, the fixing terminal 136 is connected to the connection terminal 146 and supplies power of the power supply part 150 to the first heating wire 140 to heat the first heating wire 140.

Moreover, for more safe, the air suction pump of the present invention may further include a switch part (not shown) that controls a connection between the power supply part 150 and the fixing terminal 136.

The switch part is driven by a user in a turn-on/off type, and connects or disconnects the power supply part 150 and the fixing terminal 136. Therefore, a user controls a current supplied to the first heating wire 140, thus doubly and safely preventing the first heating wire 140 from being arbitrarily heated.

Unlike the present embodiment, the first heating wire 140 may be fixing-mounted under the piston member 130 to be exposed in a downward direction without ascending or descending.

In this case, the air suction pump of the present invention needs to include a switch part (not shown) that controls the supply of a current (generated by the power supply part 150) to the first heating wire 140.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 5 is a perspective view illustrating a state in which a vinyl bag has been inserted into the air suction pump according to the first embodiment of the present invention. FIG. 6 is a sectional view illustrating a state in which the vinyl bag 170 has been inserted into the air suction pump according to the first embodiment of the present invention. FIG. 7 is a sectional view illustrating a state in which the base member 110 and the piston member 130 in FIG. 6 have been dropped. FIG. 8 is a sectional view illustrating a state in which the internal air of the vinyl bag 170 is sucked by lifting the piston member 130 in FIG. 7. FIG. 9 is a sectional view illustrating a state that heat-sutures the vinyl bag 170 by dropping the piston member 130 when the discharge of the internal air of the vinyl bag 170 is completed using the air suction pump according to the first embodiment of the present invention. FIG. 10 is a perspective view illustrating the vinyl bag 170 sealed by the air suction pump according to the first embodiment of the present invention.

As illustrated in FIG. 4, in a free state, the top of the base member 110 and the bottom of the housing 120 are separated from each other by the elastic force of the first spring 116.

An embossing 171 is formed at an inner side surface of the vinyl bag 170, and the discharge hole 175 is formed in the top of the vinyl bag 170. Food is put into the vinyl bag 170 through an opening thereof, and then the opening of the vinyl bag 170 is sealed.

In a method of sealing the opening, the opening is heat-sutured with a separate sealing apparatus, or, as described above, the opening is heat-sutured with a sealing apparatus 160 mounted on the handle part 138 or the housing 120.

That is, the opening of the vinyl bag 170 is sealed by heating the sealing heating wire 162 mounted on the sealing apparatus 160.

When a zipper bag is used, the opening of the zipper bag is sealed with a zipper.

Subsequently, as illustrated in FIGS. 5 and 6, the vinyl bag 170 is disposed between the top of the base member 110 and the bottom of the housing 120.

In FIG. 5, a heat suture line S is shown at a portion adjacent to the opening of the vinyl bag 170.

Furthermore, when disposing the vinyl bag 170 between the base member 110 and the housing 120, as illustrated in FIG. 5, a portion in which the embossing 171 of the vinyl bag 170 is formed is disposed.

In this case, with the position display part I formed at the base member 110, a user disposes the discharge hole 175 (formed in the vinyl bag 170) at the position display part I.

To discharge the internal air of the vinyl bag 170 to the outside, as illustrated in FIG. 7, the housing 120 and the piston member 130 are dropped.

When the housing 120 descends, the inside of each of the first and second packing members 112 and 122, namely, the inside of the housing 120 is cut off from the outside by the first and second packing members 112 and 122.

However, the inside of the vinyl bag 170 is connected to the inside and outside of each of the first and second packing members 112 and 122 by the embossing 171.

Therefore, as described below, the internal air of the vinyl bag 170 may flux between the embossing 171.

The discharge hole 175 connects the inside of the vinyl bag 170 and the inside of the housing 120 by the drop of the housing 120.

At this point, the switch part is in a turn-off state, and the connection terminal 146 and the fixing terminal 136 are separated from each other. Therefore, the first heating wire 140 is in a unheated state.

In this state, as illustrated in FIG. 8, when lifting the piston member 130, the internal air of the vinyl bag 170 fluxes into the housing 120 through the discharge hole 175, and when dropping the piston member 130, the internal air of the housing 120 is discharged to the outside by the principle of a general manual hand pump.

The internal air of the vinyl bag 170 is all discharged to the outside by the vertical reciprocating motion of the piston member 130.

When the discharge of the internal air of the vinyl bag 170 is completed, as illustrated in FIG. 9, the user presses the piston member 130 harder than the illustrated state of FIG. 7.

Then, at first, as illustrated in FIG. 7, when the second spring 135 has been expanded, the first heating wire 140 contacts the top of the vinyl bag 170, and, as the user further drops the piston member 130, the piston member 130 and the coupling member 133 other than the ascending/descending member 132 with the first heating wire 140 mounted thereon further descend while compressing the second spring 135 because the first heating wire 140 cannot descend any longer.

Therefore, as illustrated in FIG. 9, the connection terminal 146 contacts the fixing terminal 136, and thus, a current generated by the power supply part 150 is applied to the first heating wire 140, thereby heating the first heating wire 140.

When the switch part (not shown) that controls a connection state between the power supply part 150 and the fixing terminal 136 is mounted on the air suction pump of the present invention, by turning on the switch part, the first heating wire 140 is heated.

The first heating wire 140 and the first pressurization projection 113 strongly presses the vinyl bag 170 disposed therebetween to heat-seal the vinyl bag 170.

In this case, since the first heating wire 140 is formed in a ring shape with respect to the position display part I and the discharge hole 175 of the vinyl bag 170 is disposed at the position display part I, the circumference of the discharge hole 175 of the vinyl bag 170 is heat-sutured in a closed curve shape.

To this end, the diameter of the first heating wire 140 is required to be greater than that of the discharge hole 175.

Thus, the vinyl bag 170 is sealed in a vacuum-applied state.

When the user releases the housing 120 and the piston member 130, the housing 120 and the piston member 130 ascends by the springback force of the compressed first spring 116, and the user takes out the vinyl bag 170 between the base member 110 and the housing 120.

In FIG. 10, the vinyl bag 170 of which heat sealing is completed by the air suction pump of the present invention is illustrated.

As illustrated in FIG. 10, the discharge hole 175 is formed in the vinyl bag 170, the heat suture line S is formed at a portion adjacent to the opening and the circumference of the discharge hole 170.

The above-described embodiments of present invention may be applied to general vinyl bags on which the check valve is not mounted, and thus are economic.

Second Embodiment

FIG. 11 is an exploded perspective view illustrating an air suction pump according to a second embodiment of the present invention. FIG. 12 is a sectional view illustrating the air suction pump according to the second embodiment of the present invention.

Comparing the second embodiment with the first embodiment, particularly, there is a difference in the position of the first heating wire 140, and thus, the following description will be focused on the difference.

The air suction pump according to the second embodiment of the present invention includes a base member 110, a housing 120, a piston member 130, a first heating wire 140, and a power supply part 150.

A position display part I is formed at a top of the base member 110, and the first heating wire 140 having a ring shape is mounted to be exposed in a vertical direction with respect to the position display part I.

Furthermore, the guide projection 115 and the first spring 116 are the same as the above-described first embodiment, and thus, their detailed description is not provided.

The housing 120 is the same as the above-described first embodiment, and thus, their detailed description is not provided.

A ring shape of second pressurization projection 137 corresponding to the first heating wire 140 is protrusion-formed under the piston member 130.

Furthermore, the power supply part 150 may be built in the piston member 130 and connected to the first heating wire 140. However, in the present embodiment, the power supply part 150 is mounted on the base member 110 and connected to the first heating wire 140.

Moreover, in the second embodiment, the air suction pump of the present invention needs to include a switch part (not shown) that controls the supply of a current (generated by the power supply part 150) to the first heating wire 140.

The switch part is driven by a user in a turn-on/off type, and connects or disconnects the power supply part 150 and the first heating wire 140.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 13 is a sectional view illustrating a state in which the vinyl bag 170 has been inserted into the air suction pump according to the second embodiment of the present invention. FIG. 14 is a sectional view illustrating a state in which the base member 110 and the piston member 130 in FIG. 13 have been dropped. FIG. 15 is a sectional view illustrating a state in which the internal air of the vinyl bag 170 is sucked by lifting the piston member 130 in FIG. 14. FIG. 16 is a sectional view illustrating a state that heat-sutures the vinyl bag 170 by dropping the piston member 130 when the discharge of the internal air of the vinyl bag 170 is completed using the air suction pump according to the second embodiment of the present invention.

Even in the second embodiment of the present invention, as illustrated in FIG. 12, in a free state, the top of the base member 110 and the bottom of the housing 120 are separated from each other by the elastic force of the first spring 116.

Food is put into the vinyl bag 170 through an opening thereof, and then the opening of the vinyl bag 170 is sealed.

Subsequently, as illustrated in FIG. 13, the vinyl bag 170 is disposed between the top of the base member 110 and the bottom of the housing 120.

To discharge the internal air of the vinyl bag 170 to the outside, as illustrated in FIG. 14, the housing 120 and the piston member 130 are dropped.

When the housing 120 descends, the inside of each of the first and second packing members 112 and 122 is cut off from the outside by the first and second packing members 112 and 122.

Furthermore, due to the drop of the housing 120, the discharge hole 175 connects the inside of the vinyl bag 170 and the inside of the housing 120.

At this point, the switch part is in a turn-off state, and thus, the first heating wire 140 is in a unheated state.

In this state, as illustrated in FIG. 15, when lifting the piston member 130, the internal air of the vinyl bag 170 fluxes into the housing 120 through the discharge hole 175, and when dropping the piston member 130, the internal air of the housing 120 is discharged to the outside by the principle of a general manual hand pump.

The internal air of the vinyl bag 170 is all discharged to the outside by the vertical reciprocating motion of the piston member 130.

When the discharge of the internal air of the vinyl bag 170 is completed, as illustrated in FIG. 16, the user presses the piston member 130 harder than the illustrated state of FIG. 14.

Then, as illustrated in FIG. 16, the vinyl bag 170 disposed between the first heating wire 140 and the second pressurization projection 137 is hard pressed.

In this state, by turning on the switch part, the first heating wire 140 is heated.

As the first heating wire 140 is heated, the vinyl bag 170 is heat-sealed.

In this case, since the first heating wire 140 is formed in a ring shape with respect to the position display part I and the discharge hole 175 of the vinyl bag 170 is disposed at the position display part I, the circumference of the discharge hole 175 of the vinyl bag 170 is heat-sutured in a closed curve shape by the first heating wire 240.

Thus, the vinyl bag 170 is sealed in a vacuum-applied state.

When the user releases the housing 120 and the piston member 130, the housing 120 and the piston member 130 ascends by the springback force of the compressed first spring 116, and the user takes out the vinyl bag 170 between the base member 110 and the housing 120.

The above-described embodiments of present invention may be applied to general vinyl bags on which the check valve is not mounted, and thus are economic.

Third Embodiment

FIG. 17 is a perspective view illustrating a main configuration of an air suction pump according to a third embodiment of the present invention. FIG. 18 is a plan view illustrating a state in which a first heating wire 140 and a vinyl bag 170 are disposed according to the third embodiment of the present invention. FIG. 19 is a perspective view illustrating the vinyl bag 170 sealed by the air suction pump according to the third embodiment of the present invention.

Comparing the third embodiment with the first embodiment, particularly, there is a difference in the position of the first heating wire 140, and the other elements are similar. Therefore, the following description will be focused on the first heating wire 140.

The first heating wire 140, as illustrated in FIGS. 17 and 18, is formed in an opened curve in which one side of the first heating wire 140 is opened.

In the present embodiment, the first heating wire 140 is formed in a horse-hoof shape.

The first heating wire 140 has a diameter greater than that of the discharge hole 175, and is mounted under the ascending/descending member 132.

As illustrated in FIG. 18, when the vinyl bag 170 is disposed between the housing 120 and the base member 110, both ends of the first heating wire 140 are disposed at a junction portion P in which the top and bottom of the vinyl bag 170 join, and thus, a junction position P of the first heating wire 140 and vinyl bag 170 forms a closed curve.

Furthermore, the discharge hole 175 is disposed inside the first heating wire 140 having an arc shape and the junction portion P of the vinyl bag 170.

Therefore, when the first heating wire 140 heat-sutures the vinyl bag 170, as illustrated in FIG. 19, the discharge hole 175 is disposed inside a heating suture line S formed by the first heating wire 140 and a closed curve that the junction portion P of the vinyl bag 170 forms, thereby preventing external air from fluxing into the vinyl bag 170 through the discharge hole 175.

The other elements are the same as the first embodiment of the present invention, and thus, their detailed description is not provided.

Fourth Embodiment

FIG. 20 is an exploded perspective view illustrating an air suction pump according to a fourth embodiment of the present invention.

Comparing the fourth embodiment with the third embodiment, particularly, there is a difference in forming the first heating wire 140, and the other elements are similar. Therefore, the following description will be focused on the first heating wire 140.

The first heating wire 140, as illustrated in FIG. 20, is formed in an opened curve shape in which one side of the first heating wire 140 is opened, and mounted on the base member 110.

The shape of the first heating wire 140 is the same as the above-described third embodiment of the present invention.

In the fourth embodiment of the present invention, heat sealing by the first heating wire 140 and the formation of the discharge hole 175 are the same as the third embodiment of FIGS. 18 and 19, and thus, their detailed description is not provided.

Fifth Embodiment

FIG. 21 is a perspective view illustrating an air suction pump according to a fifth embodiment of the present invention. FIG. 22 is an exploded perspective view illustrating the air suction pump according to the fourth embodiment of the present invention. FIG. 23 is a sectional view illustrating the air suction pump according to a fifth embodiment of the present invention. FIG. 24 is a perspective view illustrating a punch member and an ascending/descending member according to the fifth embodiment of the present invention.

As illustrated in FIGS. 21 to 24, the air suction pump of the present invention in which a punch projection is formed includes a base member 210, a housing 220, a piston member 230, a first heating wire 240, and a power supply part 250.

The base member 210 is a part that is supported by a bottom. A receiving groove 211, in which the below-described punch projection 234 is placed, is formed at the center of a top of the base member 210.

Furthermore, a ring shape of first pressurization projection 213 surrounding the receiving groove 211 and a ring shape of first packing member 212 surrounding the first pressurization projection 213 are mounted on the top of the base member 210.

Moreover, a guide projection 215 is formed to protrude in a vertical direction, at a side surface of the base member 210.

The housing 220 is mounted on the base member 210 to be movable in the vertical direction. A top and a bottom of the housing 220 are opened.

A ring shape of second packing member 222 corresponding to the first packing member 212 is mounted on the bottom of the housing 220.

A guide part 225, into which the guide projection 215 is inserted and slides, is formed at the housing 220.

The guide part 225 is opened in a downward direction such that the guide projection 215 is inserted into the guide part 225 in a below direction.

Furthermore, a first spring 216 is mounted on a top of the guide projection 215, and elastic-supports the base member 210 and the housing 220 in a direction deviating from each other.

That is, the first spring 216 is mounted on the guide projection 215 and on an inner side surface of the guide part 225, and a bottom of the housing 220 is separated from a top of the base member 210 in the vertical direction in a free state.

A catching projection is formed at an upper end of the guide projection 215, and a catching jaw, by which the catching projection is caught, is formed at an inner side surface of the guide part 225. Therefore, the guide projection 225 is inserted into the guide part 225, and prevents the housing 220 and the base member 210 from being arbitrarily decoupled from each other.

The piston member 230 is disposed inside the housing 220, and an upper portion of the piston member 230 passes through the top of the housing 220 and is exposed to the outside. A handle part 238 is formed on the piston member 230.

A separate sealing apparatus 260, as illustrated in FIGS. 21 to 23, may be mounted on the piston member 230, and may heat-seal an opening of the vinyl bag 270.

In this case, the sealing apparatus 260 includes a cover member 261 that ascends or descends through the handle part 238, and a sealing heating wire 262 that is disposed under the cover member 261 and exposed to the outside when the cover member 261 descends.

The sealing heating wire 262 may be connected to the power supply part 250. When necessary, the sealing heating wire 262 may be heated by the power supply part 250.

The sealing apparatus 260 may be mounted in various structures, in addition to the illustrated of FIGS. 21 to 23.

The first heating wire 240 is formed in a closed curve shape, and mounted to be exposed in a lower direction of the piston member 230.

In the present embodiment, the first heating wire 240 is formed in a ring shape.

In this case, the first heating wire 240 is disposed inside the first packing member 212 and the second packing member 222.

Unlike the present embodiment, the first heating wire 240 may be mounted on a bottom of the housing 220 to be exposed to the outside.

The power supply part 250 supplies power to the first heating wire 240. In the present embodiment, the power supply part 250 is built in the piston member 230.

The power supply part 250 supplies the first heating wire 240 and the sealing apparatus 260 mounted on the piston member 230.

A supporting part 231, on which a fixing terminal 236 connected to the power supply part 250 is mounted, is formed inside the piston member 230.

Furthermore, an ascending/descending member 232 is mounted under the piston member 230 to be movable in the vertical direction.

The ascending/descending member 232 protrudes in a downward direction further than the bottom of the piston member 230. The ring shape of first heating wire 240 is mounted under the ascending/descending member 232 to be exposed in a downward direction.

In this case, the diameter of the first heating wire 240 is equal to that of the first pressurization projection 213, and thus, the first heating wire 240 may contact the first pressurization projection 213 when the piston member 230 descends.

A punch member 233, in which the punch projection 234 is formed to protrude in a downward direction, is disposed under the ascending/descending member 232.

The punch projection 234 is formed sharply, and thus, as described below, the punch projection 234 cuts the vinyl bag 270 disposed between the housing 220 and the base member 210 when the piston member 230 descends, thereby connecting the inside of the vinyl bag 270 and the inside of the housing 220.

The punch projection 234 cuts the vinyl bag 270, and then is inserted into the receiving groove 211 formed in the base member 210.

The punch member 233 is disposed inside the first heating wire 240.

To this end, a concave groove is formed in the center of the ascending/descending member 232, and the punch member 233 is disposed in the concave groove.

Furthermore, the first heating wire 240 is mounted on a bottom of an outer circumference surface of the ascending/descending member 232, around the punch projection 234.

The punch projection 234 further protrudes in a downward direction than the first heating wire 240, and thus, the punch projection 234 reaches the vinyl bag 270 disposed thereunder prior to the first heating wire 240, thereby allowing the vinyl bag 270 to be cut.

A second spring 235, which elastic-supports the ascending/descending member 232 in the coupling member 233 direction, is disposed between the supporting part 231 and the ascending/descending member 232.

Moreover, a connection terminal 246, which passes through the ascending/descending member 232 and is extended in the fixing terminal 236, is formed at the first heating wire 240.

Therefore, in a free state, the fixing terminal 236 and the connection terminal 246 are separated from each other by the elastic force of the second spring 235, and, when the ascending/descending member 232 moves in the vertical direction, the fixing terminal 236 is connected to the connection terminal 246 and supplies power of the power supply part 250 to the first heating wire 240 to heat the first heating wire 240.

Moreover, for more safe, the air suction pump of the present invention may further include a switch part (not shown) that controls a connection between the power supply part 250 and the fixing terminal 236.

The switch part is driven by a user in a turn-on/off type, and connects or disconnects the power supply part 250 and the fixing terminal 236. Therefore, a user controls a current supplied to the first heating wire 240, thus doubly and safely preventing the first heating wire 240 from being arbitrarily heated.

Unlike the present embodiment, the punch projection 234 may be downwardly protrusion-formed under the piston member 230 as one body without ascending or descending, and may enable the first heating wire 240 to be fixing-mounted under the piston member 230 to be exposed in a downward direction.

In this case, the air suction pump of the present invention needs to include a switch part (not shown) that controls the supply of a current (generated by the power supply part 250) to the first heating wire 240.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 25 is a perspective view illustrating a state in which a vinyl bag has been inserted into the air suction pump according to the fifth embodiment of the present invention. FIG. 26 is a sectional view illustrating a state in which the vinyl bag 270 has been inserted into the air suction pump according to the fifth embodiment of the present invention. FIG. 27 is a sectional view illustrating a state in which a discharge hole 275 has been formed in the vinyl bag 270 by dropping the base member 210 and the piston member 230 in FIG. 26. FIG. 28 is a sectional view illustrating a state in which the internal air of the vinyl bag 270 is sucked by lifting the piston member 230 in FIG. 27. FIG. 29 is a sectional view illustrating a state that heat-sutures the vinyl bag 270 by dropping the piston member 230 when the discharge of the internal air of the vinyl bag 270 is completed using the air suction pump according to the fifth embodiment of the present invention. FIG. 30 is a perspective view illustrating the vinyl bag 270 sealed by the air suction pump according to the fifth embodiment of the present invention.

As illustrated in FIG. 24, in a free state, the top of the base member 210 and the bottom of the housing 220 are separated from each other by the elastic force of the first spring 216.

An embossing 271 is formed at an inner side surface of the vinyl bag 270, and the discharge hole 275 is formed in the top of the vinyl bag 270. Food is put into the vinyl bag 270 through an opening thereof, and then the opening of the vinyl bag 270 is sealed.

In a method of sealing the opening, the opening is heat-sutured with a separate sealing apparatus, or, as described above, the opening is heat-sutured with a sealing apparatus 260 mounted on the handle part 238 or the housing 220.

That is, the opening of the vinyl bag 270 is sealed by heating the sealing heating wire 262 mounted on the sealing apparatus 260.

When a zipper bag is used, the opening of the zipper bag is sealed with a zipper.

Subsequently, as illustrated in FIGS. 25 and 26, the vinyl bag 270 is disposed between the top of the base member 210 and the bottom of the housing 220.

In FIG. 25, a heat suture line S is shown at a portion adjacent to the opening of the vinyl bag 270.

Furthermore, when disposing the vinyl bag 270 between the base member 210 and the housing 220, as illustrated in FIG. 25, a portion in which the embossing 271 of the vinyl bag 270 is formed is disposed.

The discharge hole 275 may be initially formed in the top of the vinyl bag 270. Alternatively, as in the present invention, the discharge hole 275 is not initially formed, and afterwards, the discharge hole 275 may be formed by the punch projection 234.

To discharge the internal air of the vinyl bag 270 to the outside, as illustrated in FIG. 27, the housing 220 and the piston member 230 are dropped.

When the housing 220 descends, the inside of each of the first and second packing members 212 and 222, namely, the inside of the housing 220 is cut off from the outside by the first and second packing members 212 and 222.

However, the inside of the vinyl bag 270 is connected to the inside and outside of each of the first and second packing members 212 and 222 by the embossing 271.

Therefore, as described below, the internal air of the vinyl bag 270 may flux between the embossing 271.

Furthermore, by the drop of the piston member 230, the punch projection 234 passes through the vinyl bag 270 and is inserted into the receiving groove 211.

The punch projection 234 is cut by the drop of the punch projection 234, and thus, the discharge hole 275 is formed and connects the inside of the vinyl bag 270 and the inside of the housing 220.

At this point, the switch part is in a turn-off state, and the connection terminal 246 and the fixing terminal 236 are separated from each other. Therefore, the first heating wire 240 is in a unheated state.

In this state, as illustrated in FIG. 28, when lifting the piston member 230, the internal air of the vinyl bag 270 fluxes into the housing 220 through the discharge hole 275, and when dropping the piston member 230, the internal air of the housing 220 is discharged to the outside by the principle of a general manual hand pump.

The internal air of the vinyl bag 270 is all discharged to the outside by the vertical reciprocating motion of the piston member 230.

When the discharge of the internal air of the vinyl bag 270 is completed, as illustrated in FIG. 29, the user presses the piston member 230 harder than the illustrated state of FIG. 27.

Then, at first, as illustrated in FIG. 27, when the second spring 235 has been expanded, the first heating wire 240 contacts the top of the vinyl bag 270, and, as the user further drops the piston member 230, the piston member 230 and the coupling member 233 other than the ascending/descending member 232 with the first heating wire 240 mounted thereon further descend while compressing the second spring 235 because the first heating wire 240 cannot descend any longer.

Therefore, as illustrated in FIG. 29, the connection terminal 246 contacts the fixing terminal 236, and thus, a current generated by the power supply part 250 is applied to the first heating wire 240, thereby heating the first heating wire 240.

When the switch part (not shown) that controls a connection state between the power supply part 250 and the fixing terminal 236 is mounted on the air suction pump of the present invention, by turning on the switch part, the first heating wire 240 is heated.

The first heating wire 240 and the first pressurization projection 213 strongly presses the vinyl bag 270 disposed therebetween to heat-seal the vinyl bag 270.

In this case, since the first heating wire 240 is formed in a ring shape with respect to the position display part I and the discharge hole 275 of the vinyl bag 270 is disposed at the punch projection 234, the circumference of the discharge hole 275 of the vinyl bag 270 is heat-sutured in a closed curve shape.

Thus, the vinyl bag 270 is sealed in a vacuum-applied state.

When the user releases the housing 220 and the piston member 230, the housing 220 and the piston member 230 ascends by the springback force of the compressed first spring 216, and the user takes out the vinyl bag 270 between the base member 210 and the housing 220.

In FIG. 30, the vinyl bag 270 of which heat sealing is completed by the air suction pump of the present invention is illustrated.

As illustrated in FIG. 30, the discharge hole 275 is formed in the vinyl bag 270, the heat suture line S is formed at a portion adjacent to the opening and the circumference of the discharge hole 270.

The above-described embodiments of present invention may be applied to general vinyl bags on which the check valve is not mounted, and thus are economic.

Sixth Embodiment

FIG. 31 is an exploded perspective view illustrating an air suction pump according to a sixth embodiment of the present invention. FIG. 32 is a sectional view illustrating the air suction pump according to the sixth embodiment of the present invention.

Comparing the sixth embodiment with the fifth embodiment, particularly, there is a difference in the position of the first heating wire 240, and thus, the following description will be focused on the difference.

The air suction pump according to the second embodiment of the present invention includes a base member 210, a housing 220, a piston member 230, a first heating wire 240, and a power supply part 250.

A receiving groove 211 is formed in a top of the base member 210, and the first heating wire 240 having a ring shape is mounted to be exposed in a vertical direction with respect to the receiving groove 211.

Furthermore, the guide projection 215 and the first spring 216 are the same as the above-described fifth embodiment, and thus, their detailed description is not provided.

The housing 220 is the same as the above-described fifth embodiment, and thus, their detailed description is not provided.

The punch projection 234 is formed to protrude in a downward direction, under the piston member 230. A second pressurization projection 237 corresponding to the first heating wire 240 is protrusion-formed around the punch projection 237.

Furthermore, the power supply part 250 may be built in the piston member 230 and connected to the first heating wire 240. However, in the present embodiment, the power supply part 250 is mounted on the base member 210 and connected to the first heating wire 240.

Moreover, in the sixth embodiment, the air suction pump of the present invention needs to include a switch part (not shown) that controls the supply of a current (generated by the power supply part 250) to the first heating wire 240.

The switch part is driven by a user in a turn-on/off type, and connects or disconnects the power supply part 250 and the first heating wire 240.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 33 is a sectional view illustrating a state in which the vinyl bag 270 has been inserted into the air suction pump according to the sixth embodiment of the present invention. FIG. 34 is a sectional view illustrating a state in which the discharge hole 275 has been formed in the vinyl bag 270 by dropping the base member 210 and the piston member 230 in FIG. 33. FIG. 35 is a sectional view illustrating a state in which the internal air of the vinyl bag 270 is sucked by lifting the piston member 230 in FIG. 34. FIG. 36 is a sectional view illustrating a state that heat-sutures the vinyl bag 270 by dropping the piston member 230 when the discharge of the internal air of the vinyl bag 270 is completed using the air suction pump according to the sixth embodiment of the present invention.

Even in the sixth embodiment of the present invention, as illustrated in FIG. 32, in a free state, the top of the base member 210 and the bottom of the housing 220 are separated from each other by the elastic force of the first spring 216.

Food is put into the vinyl bag 270 through an opening thereof, and then the opening of the vinyl bag 270 is sealed.

Subsequently, as illustrated in FIG. 33, the vinyl bag 270 is disposed between the top of the base member 210 and the bottom of the housing 220.

To discharge the internal air of the vinyl bag 270 to the outside, as illustrated in FIG. 34, the housing 220 and the piston member 230 are dropped.

When the housing 220 descends, the inside of each of the first and second packing members 212 and 222 is cut off from the outside by the first and second packing members 212 and 222.

Furthermore, due to the drop of the piston member 230, the punch projection 234 pass through the vinyl bag 270 and is inserted into the receiving groove 211.

Therefore, the discharge hole 275 is formed in the vinyl bag 270, and connects the inside of the vinyl bag 270 and the inside of the housing 220.

At this point, the switch part is in a turn-off state, and thus, the first heating wire 240 is in a unheated state.

In this state, as illustrated in FIG. 35, when lifting the piston member 230, the internal air of the vinyl bag 270 fluxes into the housing 220 through the discharge hole 275, and when dropping the piston member 230, the internal air of the housing 220 is discharged to the outside by the principle of a general manual hand pump.

The internal air of the vinyl bag 270 is all discharged to the outside by the vertical reciprocating motion of the piston member 230.

When the discharge of the internal air of the vinyl bag 270 is completed, as illustrated in FIG. 36, the user presses the piston member 230 harder than the illustrated state of FIG. 34.

Then, as illustrated in FIG. 36, the vinyl bag 270 disposed between the first heating wire 240 and the second pressurization projection 237 is hard pressed.

In this state, by turning on the switch part, the first heating wire 240 is heated.

As the first heating wire 240 is heated, the vinyl bag 270 is heat-sealed.

In this case, since the first heating wire 240 is formed in a ring shape with respect to the punch projection 234 and the receiving groove 211, the circumference of the discharge hole 275 of the vinyl bag 270 is heat-sutured in a closed curve shape by the first heating wire 240.

Thus, the vinyl bag 270 is sealed in a vacuum-applied state.

When the user releases the housing 220 and the piston member 230, the housing 220 and the piston member 230 ascends by the springback force of the compressed first spring 216, and the user takes out the vinyl bag 270 between the base member 210 and the housing 220.

The above-described embodiments of present invention may be applied to general vinyl bags on which the check valve is not mounted, and thus are economic.

Seventh Embodiment

FIG. 37 is a perspective view illustrating a main configuration of an air suction pump according to a seventh embodiment of the present invention. FIG. 38 is a plan view illustrating a state in which a first heating wire 240 and a vinyl bag 270 are disposed according to the seventh embodiment of the present invention. FIG. 39 is a perspective view illustrating the vinyl bag 270 sealed by the air suction pump according to the seventh embodiment of the present invention.

Comparing the seventh embodiment with the fifth embodiment, particularly, there is a difference in the position of the first heating wire 240, and the other elements are similar. Therefore, the following description will be focused on the first heating wire 240.

The first heating wire 240, as illustrated in FIGS. 37 and 38, is formed in an opened curve in which one side of the first heating wire 240 is opened.

In the present embodiment, the first heating wire 240 is formed in a horse-hoof shape.

The first heating wire 240 partially surrounds the circumference of the punch projection 234 and is disposed under the ascending/descending member 232.

As illustrated in FIG. 38, when the vinyl bag 270 is disposed between the housing 220 and the base member 210, both ends of the first heating wire 240 are disposed at a junction portion P in which the top and bottom of the vinyl bag 270 join, and thus, a junction position P of the first heating wire 240 and vinyl bag 270 forms a closed curve.

Furthermore, the discharge hole 275 is disposed inside the first heating wire 240 having an arc shape and the junction portion P of the vinyl bag 270.

Therefore, when the first heating wire 240 heat-sutures the vinyl bag 270, as illustrated in FIG. 39, the discharge hole 275 is disposed inside a heating suture line S formed by the first heating wire 240 and a closed curve that the junction portion P of the vinyl bag 270 forms, thereby preventing external air from fluxing into the vinyl bag 270 through the discharge hole 275.

The other elements are the same as the fifth embodiment of the present invention, and thus, their detailed description is not provided.

Eighth Embodiment

FIG. 40 is an exploded perspective view illustrating an air suction pump according to an eighth embodiment of the present invention.

Comparing the eighth embodiment with the seventh embodiment, particularly, there is a difference in forming the first heating wire 240, and the other elements are similar. Therefore, the following description will be focused on the first heating wire 240.

The first heating wire 240, as illustrated in FIG. 40, is formed in an opened curve shape in which one side of the first heating wire 240 is opened, and mounted on the base member 210.

The shape of the first heating wire 240 is the same as the above-described seventh embodiment of the present invention.

In the eighth embodiment of the present invention, heat sealing by the first heating wire 240 and the formation of the discharge hole 275 are the same as the seventh embodiment of FIGS. 38 and 39, and thus, their detailed description is not provided.

Ninth Embodiment

FIG. 41 is a perspective view illustrating an air suction pump according to a ninth embodiment of the present invention. FIG. 42 is a one-directional exploded perspective view illustrating the air suction pump according to the ninth embodiment of the present invention. FIG. 43 is an other-directional exploded perspective view illustrating the air suction pump according to the ninth embodiment of the present invention. FIG. 44 is a sectional view taken along line A-A of FIG. 41. FIG. 45 is a sectional view taken along line B-B of FIG. 41.

As illustrated in FIGS. 41 to 45, the air suction pump of the present invention includes a base member 310, a housing 320, a piston member 330, a first heating wire 340, a power supply part 350, and a main gasket 360.

The base member 310 includes a support 311 in which a top of the support 311 is opened and a receiving part 319 is formed inside the support 311, and a cover member 312 that is attachably/detachably coupled to the top of the support 311.

The receiving part 319, as described below, receives a foreign material discharged from a vinyl bag 370. In the ninth embodiment of the present invention, the support 311 and the receiving part 319 are separately formed. However, the support 311 and the receiving part 319 may be formed as one body.

The receiving part 319 is opened in an upward direction. When the piston member 330 moves upward and downward in a state in which the vinyl bag 370 has been disposed through the opened front between the base member 310 and the housing 320, the foreign material discharged from the vinyl bag 370 is placed in the receiving part 319.

The support 311 becomes progressively broader in a downward direction, and thus is stably disposed at a bottom. As illustrated in FIG. 41, the support 311 acts as a buttress that stably supports the air suction pump of the present invention overall.

The cover member 312 covers a top of the support 311, and specifically, a top of the receiving part 319.

When the cover member 312 is disposed to cover the top of the receiving part 319, a contact portion of the cover member 312 and receiving part 319 blocks the influx and outflux of air through a separate sealing means.

A suction hole 313 and a discharge hole 313, which connect the receiving part 319 and the outside, are formed in the cover member 312, and a guide projection 317 is protrusion-formed in an upward direction.

The suction hole 313 and the discharge hole 314 are separated from each other, and a lower block gasket 318 is mounted around the suction hole 313. Thus, as described below, when the housing 320 descends, the lower block gasket 318 blocks a connection path of the suction hole 313 and the discharge hole 314.

A check valve 315, which moves even when air moves in an upward direction inside the receiving part 319, is mounted on the discharge hole 314.

A generally known check valve may be used as the check valve 315, and thus, its detailed structural description is not provided.

The discharge hole 314 is formed more rearward than the suction hole 313, namely, in a direction opposite to a direction in which the vinyl bag 370 is inserted. In inserting the vinyl bag 370, the vinyl bag 370 may not cover the discharge hole 314.

In the ninth embodiment of the present invention, to prevent that the vinyl bag 370 covers the discharge hole 314 and thus the discharge hole 314 is not opened, a groove 316 connected to the discharge hole 314 is formed in the cover member 312.

Moreover, a stopper projection 311 a deterring the movement of the vinyl bag 370 is formed to protrude in an upward direction, in the base member 310.

The stopper projection 311 a may be formed at the support 311 or the cover member 312.

In the ninth embodiment of the present invention, the stopper projection 311 a is upwardly protrusion-formed in an arc shape along an outer circumference surface of the support 311.

The stopper projection 311 a is disposed more rearward from the suction hole 313.

Therefore, as described below, in inserting the vinyl bag 370, the stopper projection 311 a allows the vinyl bag 370 to be inserted only by any degree, and allows the suction hole 313 to be disposed across.

A second spring 317 a is inserted into the guide projection 317, and enables the housing 320 to be mounted on the base member 310 to be movable in a vertical direction.

The housing 320 is formed in a hollow cylinder shape whose a top and a bottom are opened.

A punch projection 321 is downwardly protrusion-formed under the housing 320.

When the housing 320 descends, the vinyl bag 370 disposed between the housing 320 and the cover member 312 is cut, and then the punch projection 321 is inserted into the suction hole 313, thereby connecting the vinyl bag 370 and the receiving part 319 through the suction hole 313.

The punch projection 321 may not be formed in the housing 320, and, by separately forming a hole in the vinyl bag 370, the vinyl bag 370 may be disposed for the hole to be connected to the suction hole 313.

However, as in the present invention, the punch projection 321 is formed in the housing 320, and, by cutting the vinyl bag 370 with the punch projection 321, the vinyl bag 370 may be connected to the receiving part 319 through the suction hole 313.

An upper block gasket 328 is disposed around the punch projection 321, and, when the housing 320 descends, a cut portion 375 of the vinyl bag 370 (which has been cut by the punch projection 321) except the suction hole 313 is blocked from the outside by the upper block gasket 328 and the lower block gasket 318.

Therefore, the internal air of the vinyl bag 370 necessarily moves to the receiving part 319 through the suction hole 313.

That is, air discharged from the vinyl bag 370 moves to under the piston 330 disposed inside the housing 320, through the suction hole 313, the receiving part 319, and the discharge hole 314.

The piston member 330 is disposed to be movable upward and downward, inside the housing 320, and a top of the piston member 330 passes through a top of the housing 320 and is exposed to the outside.

The piston member 330 includes a piston part 331, a load part 332, a handle part 333, a pressurization member 334, and a first spring 335.

The piston part 331 has the same shape as that of an inner surface of the housing 320, and a rubber ring 331 a is mounted on an outer circumference surface of the piston part 331 and contacts the inner surface of the housing 320.

The load part 332 is formed in a rod shape, and coupled to a top of the piston part 331. The power supply part 350 is inserted into and disposed inside the load part 332.

To mount the piston member 330 inside the housing 320, the load part 332 and the piston member 330 may be separately manufactured and assembled.

The handle part 333 is formed to be exposed to the outside, on the load part 332.

A second heating wire 339 is included in the handle part 333, and a sealing part 338 for heat-suturing an opening 371 of the vinyl bag 370 is formed at the handle part 333.

The second heating wire 339 is connected to the power supply part 350, and thus, with the vinyl bag 370 being inserted into the sealing part 338, when the second heating wire 339 is pressed and connected to the power supply part 350, the vinyl bag 370 is heat-sealed by heating the second heating wire 339.

To this end, as illustrated in FIG. 52, a third terminal 339 a connected to the power supply part 350 is formed at the handle part 333, and disposed under the second heating wire 339. When the second heating wire 339 descends, the second heating wire 339 contacts the third terminal 339 a to supply the power of the power supply part 350 to the second heating wire 339.

The pressurization member 334 is coupled to a bottom of the piston part 331 to be movable in a vertical direction.

The pressurization member 334 and the piston part 331 are disposed inside the housing 320.

Furthermore, the first spring 335 is disposed between the bottom of the piston part 331 and the pressurization member 334, and applies an elastic force to the pressurization member 334 in a direction deviating from the piston part 331.

The first heating wire 340 is mounted to be exposed to the outside, on at least one or more of a top of the base member 310, a bottom of the housing 320, and a lower portion of the piston member 330.

In the ninth embodiment of the present invention, the first heating wire 340 is mounted to be exposed in a downward direction, under the piston member 330, and specifically, under the pressurization member 334.

In a free state, the first heating wire 340 is not connected to the power supply part 350 by the elastic force of the first spring 335, and then, when the first heating wire 340 contacts a top of the cover member 312 and thus the first spring 335 is compressed by the drop of the piston member 330, the power supply part 350 and the first heating wire 340 are grounded, thereby heating the first heating wire 340.

To this end, a first terminal 336 is formed at a lower portion of the piston part 331, and connected to the power supply part 350. A second terminal 337 disposed under the first terminal 336 is formed on the pressurization member 334, and connected to the first heating wire 340.

In more detail, the first terminal 336 and the third terminal 339 a connected to the power supply part 350 are connected by an electrical line 339 b inserted into the piston part 331.

Therefore, a current generated by the power supply part 350 moves to the third terminal 339 a, the electrical line 339 b, and the first terminal 336.

Furthermore, the first heating wire 340 is formed in a curve shape, and disposed to surround the punch projection 321. As described below, the cut portion 375 of the vinyl bag 370 cut by the punch projection 321 is heat-sutured by the first heating wire 340.

The power supply part 350, as described above, is mounted inside the load part 332, and supplies power to the first and second heating wires 340 and 339.

The power supply part 350 may be configured with a portable battery or a secondary cell.

The main gasket 360 is protrusion-formed at a top of the base member 310 and/or a bottom of the housing 320.

In the ninth embodiment of the present invention, the main gasket 360 includes an upper main gasket 361 mounted on a bottom of the housing 320, and a lower main gasket 362 mounted on a top of the base member 310.

The upper main gasket 361 and the lower main gasket 362 are formed in a hollow cylinder shape. When the housing 320 descends, the upper main gasket 361 and the lower main gasket 362 contact each other to seal the inside of the housing 320, thereby preventing air influx/outflux between the inside of the housing and the outside.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 46 is a sectional view illustrating a state that heat-sutures the opening 371 by inserting the vinyl bag 370 into the sealing part 338 of the air suction pump according to the ninth embodiment of the present invention. FIG. 47 is a perspective view illustrating a state in which the vinyl bag 370 has been inserted between the base member 310 and the housing 320 of the air suction pump according to the ninth embodiment of the present invention. FIG. 48 is a sectional view in FIG. 47. FIG. 49 is a sectional view illustrating a state that performs pumping by dropping the housing 320 and lifting the piston member 330 in FIG. 47. FIG. 50 is a sectional view illustrating a state that heat-sutures the cut portion 375 of the vinyl bag 370 after completing the application of vacuum in the illustrated state of FIG. 49. FIG. 51 is a perspective view illustrating the vinyl bag 370 when the application of vacuum is completed by the air suction pump according to the ninth embodiment of the present invention.

In a state that is as illustrated in FIG. 41, by turning over the air suction pump except the support 311, as illustrated in FIG. 46, the sealing part 338 is disposed at the support 311.

In this state, the opening 371 of the vinyl bag 370 is inserted into the sealing part 338, and then, by pressing in a downward direction, the opening 371 of the vinyl bag 370 is heat-sutured by the second heating wire 339.

The heat-sutured portion is illustrated as a second heat suture portion 374, in FIG. 51.

Subsequently, by again turning over the air suction pump, the air suction pump returns to the illustrated state of FIGS. 41 and 44.

The vinyl bag 370 with the heat-sutured opening 371, as illustrated in FIGS. 47 and 48, is insertion-disposed through the opened front between the base member 310 and the housing 320.

In this case, as illustrated in FIG. 47, the vinyl bag 370 enables a side junction portion 372 to be insertion-disposed through the opened front between the base member 310 and the housing 320.

The housing 320 is separated from the cover member 312 by the second spring 317 a, and thus, the vinyl bag 370 is inserted into and disposed in a separation space formed between the housing 320 and the cover member 312.

The vinyl bag 370, inserted between the housing 320 and the cover member 312, is inserted by a certain length by the stopper projection 311 a, and is no longer inserted.

In this case, as illustrated in FIG. 48, the vinyl bag 370 covers the suction hole 313, and is disposed under the punch projection 321.

Although not shown, in the illustrated state of FIG. 48, the vinyl bag 370 does not cover the discharge hole 314.

In this state, as illustrated in FIG. 49, the housing 320 is dropped.

As the housing 320 descends, the punch projection 321 cuts the vinyl bag 370, and then the suction hole 313 is inserted into the vinyl bag 370.

Furthermore, the upper block gasket 328 and the lower block gasket 318 are closely adhered to each other with the vinyl bag 370 therebetween, and the cut portion 375 of the vinyl bag 370 except the suction hole 313 is blocked from the outside.

Moreover, as the housing 320 descends, the upper block gasket 328 and the lower block gasket 318 contact each other, thereby preventing air influx/outflux between the inside and outside of each of the upper block gasket 328 and the lower block gasket 318.

Subsequently, a user lifts the piston member 330.

As the piston member 330 ascends, the internal volume of the housing 320 disposed under the piston part 331 increases, and thus, the check value 315 ascends in an upward direction, thereby opening the discharge hole 314. Therefore, the internal air of the vinyl bag 370 fluxes into the housing 320 through the suction hole 313, the receiving part 319, and the discharge hole 314.

When the piston member 330 ascends and then descends, the check valve 315 descends by an air pressure to close the discharge hole 314, and, air disposed under the piston part 331 passes through an upper portion of the housing 320 and is discharged to the outside through a gap between the piston part 331 and the rubber ring 331 a mounted on an outer circumference surface of the piston part 331.

By the vertical reciprocating motion of the piston member 330, the internal air of the vinyl bag 370 is discharged to the outside.

At this point, the internal air of the vinyl bag 370 is discharged, and simultaneously liquid or powder may be discharged together. Such a material moves to the receiving part 319 through the suction hole 313 together with air and is loaded in the receiving part 319. Accordingly, the material and air cannot flux into the housing 320.

When it is determined that vacuum has been applied to the inside of the vinyl bag 370 by the pumping motion of the piston member 330, the piston member 330 is pressed and dropped.

Especially, even up to this point, the housing 320 needs to maintain a dropped state.

As the piston member 330 descends, the heating wire 340 contacts the vinyl bag 370.

However, since the first heating wire 340 is not yet connected to the power supply part 350, the first heating wire 340 is not heated.

As illustrated in FIG. 5, when the piston member 330 further descends, the pressurization member 334 with the first heating wire 340 mounted thereon cannot descend any longer, and thus, the piston part 331 compresses the first spring 335 and descends in the pressurization member 334 direction.

As the piston part 331 compresses the first spring 335 and descends in the pressurization member 334 direction, the first terminal 336 connected to the power supply part 350 and the second terminal 337 connected to the first heating wire 340 contact each other, and thus, the first heating wire 340 is heated.

By heating the first heating wire 340, as illustrated in FIG. 51, a first heat sealing portion 373 is formed around the cut portion 375 of the vinyl bag 370 cut by the punch projection 321.

In this case, the first heating wire 340 is disposed to surround the punch projection 321, and thus, the cut portion 375 of the vinyl bag 370 is blocked from the inside of the vinyl bag 370 by the first heat sealing portion 373.

Furthermore, as illustrated in FIG. 51, the first heat sealing portion 373 is connected to the side junction portion 372 of the vinyl bag 370 by the first heating wire 340.

After the vacuum applying and heat suturing of the vinyl bag 370 are completed, the receiving part 319 is separated from the support 311 and cleaned.

Tenth Embodiment

FIG. 53 is a perspective view illustrating an air suction pump according to a tenth embodiment of the present invention. FIG. 54 is a one-directional exploded perspective view illustrating the air suction pump according to the tenth embodiment of the present invention.

FIG. 55 is an other-directional exploded perspective view illustrating the air suction pump according to the tenth embodiment of the present invention. FIG. 56 is a sectional view taken along line C-C of FIG. 53. FIG. 57 is a plan view schematically illustrating the positions of a stopper projection and a first heating wire of the air suction pump according to the tenth embodiment of the present invention.

As illustrated in FIGS. 53 to 56, the air suction pump of the present invention includes a base member 410, a main gasket 420, a housing 430, a piston member 440, a first heating wire 450, a power supply part 460, and a stopper projection 470.

The base member 410 includes a support 411 in which a top of the support 411 is opened and a receiving part 412 is formed inside the support 411, and a cover member 413 that is attachably/detachably coupled to the top of the support 411.

The receiving part 412, as described below, receives a foreign material discharged from a vinyl bag 480. In the tenth embodiment of the present invention, the support 411 and the receiving part 412 are separately formed. However, the support 411 and the receiving part 412 may be formed as one body.

The receiving part 412 is opened in an upward direction. When the piston member 440 moves upward and downward in a state in which the vinyl bag 480 has been disposed through the opened front between the base member 410 and the housing 430, the foreign material discharged from the vinyl bag 480 is placed in the receiving part 412.

The support 411 becomes progressively broader in a downward direction, and thus is stably disposed at a bottom. As illustrated in FIG. 53, the support 411 acts as a buttress that stably supports the air suction pump of the present invention overall.

The cover member 413 covers a top of the support 411, and specifically, a top of the receiving part 412.

When the cover member 413 is disposed to cover the top of the receiving part 412, a contact portion of the cover member 413 and receiving part 412 blocks the influx and outflux of air through a separate sealing means.

A drop hole 414 connecting the receiving part 412 with the outside is rearward formed in the cover member 413, and disposed inside the main gasket 420. A foreign material discharged from the vinyl bag 480 is loaded in the receiving part 412 through the drop hole 414.

Furthermore, as described below, the stopper projection 470 is protrusion-formed at a top of the cover member 413.

A detailed description on the stopper projection 470 will be made below.

Moreover, a pressurization rubber 415 for pressurizing the vinyl bag 480 (which is disposed under the first heating wire 450) when the first heating wire 450 descends is mounted on a top of the cover member 413 to be protrude in an upward direction.

The main gasket 420 is formed in a closed curve shape, and protrusion-formed at a top of the base member 410 and/or a bottom of the housing 430.

In the tenth embodiment of the present invention, the main gasket 420 includes an upper main gasket 421 mounted on a bottom 431 of the housing 430, and a lower main gasket 422 mounted on a top of the base member 410.

The upper main gasket 421 and the lower main gasket 422 are formed in a hollow cylinder shape. When the housing 430 descends, the upper main gasket 421 and the lower main gasket 422 contact each other to seal the inside of the housing 430, thereby preventing air influx/outflux between the inside of the housing 430 and the outside.

As described above, the drop hole 414 is disposed inside the lower main gasket 422.

Furthermore, the stopper projection 470 may be formed outside the lower main gasket 422, but may be formed inside the lower main gasket 422.

The housing 430 is formed in a hollow cylinder shape whose a top and a bottom are opened, and, as described below, the housing 430 is mounted on the base member 410 to be movable in a vertical direction by the stopper projection 470.

The upper mina gasket 421 is mounted around the bottom 431 of the housing 430, and a suction hole 432 disposed inside the upper main gasket 421 is formed in the bottom 431 of the housing 430.

The suction hole 432 is disposed on the drop hole 414.

Moreover, a check valve 433 is mounted into the suction hole 432. The piston member 440 ascends, and only when the internal air of the vinyl bag 480 fluxes into the housing 430 through the suction hole 432, the check value 433 is opened.

A generally known check valve may be used as the check valve 433, and thus, its detailed structural description is not provided.

A first heating wire discharge hole 434, which allows the first heating wire 450 to be exposed to under the housing 430 when the piston member 440 descends, is formed in the bottom 431 of the housing 430.

The first heating wire discharge hole 434 is disposed at the front that is a direction in which the vinyl bag 480 is inserted, inside the upper main gasket 421, and disposed in a direction opposite to the suction hole 432.

Moreover, a bottom of the housing 430 may be manufactured separately from a cylinder shape of body, and then may be assembly-coupled to the body.

Block gaskets 423 and 424, which block and seal a connection path between the first heating wire discharge hole 434 and the suction hole 432 when a connection between the inside and outside of the main gasket 420 is blocked by the drop of the housing 430, are formed at a top of the base member 410 and/or the bottom 431 of the housing 430.

In this case, the suction hole 432 and the drop hole 414 maintain a connection state therebetween, a connection path between the first heating wire discharge hole 434 and the suction hole 432 is blocked and sealed, and a connection path between the first heating wire discharge hole 434 and the drop hole 414 is blocked and sealed.

In the tenth embodiment, the block gaskets 423 and 424 include a lower block gasket 424 formed at the top of the base member 410, and an upper block gasket 423 formed at the bottom 431 of the housing 430.

The lower block gasket 424 is disposed inside the lower main gasket 422. In the tenth embodiment of the present invention, the lower block gasket 424 is connected across the inside of the lower main gasket 422 having a circular shape, and the lower block gasket 424 is disposed between the drop hole 414 and the pressurization rubber 415.

The lower block gasket 424 may be provided separately from the lower main gasket 422, or, as in the tenth embodiment of the present invention, the lower block gasket 424 and the lower main gasket 422 may be provided as one body.

The upper block gasket 423 is disposed inside the upper main gasket 421. In the tenth embodiment of the present invention, and, as described above, the upper main gasket 421 is connected between the first heating wire discharge hole 434 and the suction hole 432.

The upper block gasket 423 may be provided separately from the upper main gasket 421, or, as in the tenth embodiment of the present invention, the upper block gasket 423 and the upper main gasket 421 may be provided as one body.

The piston member 440 is disposed to be movable upward and downward inside the housing 430, and a top of the piston member 440 passes through a top of the housing 430 and is exposed to the outside.

The piston member 440 includes a piston part 441, a load part 442, a handle part 443, a pressurization member 444, and a first spring 445.

The piston part 441 has the same shape as that of an inner surface of the housing 430, and a rubber ring 448 a is mounted on an outer circumference surface of the piston part 441 and contacts the inner surface of the housing 430.

The load part 442 is formed in a rod shape, and coupled to a top of the piston part 441. The power supply part 460 is inserted into and disposed inside the load part 442.

To mount the piston member 440 inside the housing 430, the load part 442 and the piston member 440 may be separately manufactured and assembled.

The handle part 443 is formed to be exposed to the outside, on the load part 442.

The pressurization member 444 is coupled to a bottom of the piston part 441 to be movable in a vertical direction.

The pressurization member 444 and the piston part 441 are disposed inside the housing 430.

Furthermore, the first spring 445 is disposed between the bottom of the piston part 441 and the pressurization member 444, and applies an elastic force to the pressurization member 444 in a direction deviating from the piston part 441.

The first heating wire 450 is mounted to be exposed to the outside, on at least one or more of a top of the base member 410, the bottom 431 of the housing 420, and a lower portion of the piston member 440.

In the tenth embodiment of the present invention, the first heating wire 450 is mounted to be exposed in a downward direction, under the piston member 440, and specifically, under the pressurization member 444.

In a free state, the first heating wire 450 is not connected to the power supply part 460 by the elastic force of the first spring 445, and then, when the first heating wire 450 contacts a top of the cover member 413 and thus the first spring 445 is compressed by the drop of the piston member 440, the power supply part 460 and the first heating wire 450 are grounded, thereby heating the first heating wire 450.

To this end, two first terminals 446 are formed at a lower portion of the piston part 441, and connected to the power supply part 460. Two second terminals 437 disposed under the first terminals 436 are formed on the pressurization member 444, and connected to the first heating wire 450.

In more detail, as illustrated in FIG. 66, two third terminals 461 are mounted on the power supply part 460, the third terminal 461 and the first terminal 446 are connected by an electrical line 462 inserted into the piston part 441.

FIG. 66 is a perspective view illustrating a connection portion between the power supply part 460 and the third terminal 461 according to the tenth embodiment of the present invention.

Therefore, a current generated by the power supply part 460 moves to the third terminal 461, the electrical line 461, and the first terminal 446.

The power supply part 460, as described above, is mounted inside the load part 442, and supplies power to the first heating wire 450.

The power supply part 460 may be configured with a portable battery or a secondary cell.

The stopper projection 470 is protrusion-formed on the base member 410 or under the housing 430, and contacts the vinyl bag 480 inserted between the base member 410 and the housing 430, thereby preventing the movement of the vinyl bag 480.

In the tenth embodiment of the present invention, the stopper projection 470 is formed to protrude in an upward direction, at a top of the cover member 413.

The stopper projection 470 has two or more contact surfaces that contact the vinyl bag 480, and the contact surfaces are separated from each other.

In the tenth embodiment of the present invention, the stopper projection 470 is configured with two stopper projections, namely, first and second stopper projections 471 and 472, which are separated from each other. Since the stopper projection 470 is configured as two, the stopper projection 470 has four contact surfaces that contact the vinyl bag 480.

The first stopper projection 471 is simply formed to protrude in an upward direction, on the cover member 413.

Furthermore, the second stopper projection 472 is upwardly protrusion-formed longer than the first stopper projection 471. When the housing 430 moves in a vertical direction, the second stopper projection 472 guides the vertical motion of the housing 430.

To this end, the second stopper projection 472 is inserted into a groove 435 formed under the housing 430, and a second spring 473 is disposed between a top of the second stopper projection 472 and the housing 430. Therefore, by the elastic force of the second spring 473, a constant gap between the housing 430 and the cover member 413 is maintained, and the housing 430 and the cover member 413 are separated from each other.

In this case, a top of groove 435 of the housing 430, into which the second stopper projection 472 is inserted, may be plugged.

Moreover, as illustrated in FIG. 65, the first and second stopper projections 471 and 472 may be connected as one body, and thus, the stopper projection 470 may be formed in an arc-shape curve. Therefore, one end of the stopper projection 470 may be separated from the other end of the stopper projection 470.

In this case, the one end and other end of the stopper projection 470 is disposed in a direction into which the vinyl bag 480 is inserted, namely, in the first heating wire 450 direction.

In this case, since the one end of the stopper projection 470 is separated from the other end of the stopper projection 470, the stopper projection 470 has two or more contact surfaces that contact the vinyl bag 480.

A virtual line L, which connects two contact surfaces most adjacent to the first heating wire 450 among the contact surfaces of the stopper projection 470, is separated from the first heating wire 450, in the rear of the first heating wire 450.

That is, the first heating wire 450 is disposed more forward than the stopper projection 470, namely, in a direction in which the vinyl bag 480 is inserted.

Hereinafter, a method of vacuum heat-suturing a vinyl bag according to the present invention having the above-described configuration will be described.

FIG. 58 is a sectional view illustrating a state of performing a first heat sealing operation that heat-sutures a portion of an opening 481 by inserting the vinyl bag 480 into the air suction pump according to the tenth embodiment of the present invention. FIG. 59 is a plan view schematically illustrating the positions of the stopper projection 470, first heating wire 450, and vinyl bag 480 in the illustrated state of FIG. 58. FIG. 60 is a perspective view illustrating the vinyl bag 480 after completing the first heat sealing operation in FIGS. 58 and 59.

As illustrated in FIGS. 58 and 59, the opening 481 of the vinyl bag 480 is inserted into a gap between the base member 410 and the housing 430.

The vinyl bag 480 is inserted between the base member 410 and the housing 430, and then contacts the stopper projection 470, whereby the vinyl bag 480 cannot move any longer.

In this case, since the stopper projection 470 includes the first stopper projection 471 and the second stopper projection 472, the stopper projection 470 has two or more contact surfaces that contact the vinyl bag 480.

A virtual line L, which connects two contact surfaces most adjacent to the first heating wire 450 among the contact surfaces of the stopper projection 470, is separated from the first heating wire 450, in the rear of the first heating wire 450. Therefore, the first heating wire 450 is disposed on the vinyl bag 480.

In FIG. 59, even the first heating wire 450 disposed on the vinyl bag 480 is illustrated.

As described above, when the insertion of the vinyl bag 480 is completed, the piston member 440 is dropped.

As the piston member 440 descends, the first heating wire 450 contacts the vinyl bag 480.

However, the first heating wire 450 is not yet connected to the power supply part 460, the first heating wire is not heated.

When the piston member 440 further descends, the first heating wire 450 and the vinyl bag 480 contact the pressurization rubber 415, and thus, the pressurization member 444 with the first heating wire 450 mounted thereon cannot descend any longer. Therefore, the piston part 441 compresses the first spring 445 and descends in the pressurization member 444 direction.

As the piston part 441 compresses the first spring 445 and descends, the first terminal 446 connected to the power supply part 460 and the second terminal 447 connected to the first heating wire 450 contact each other, and thus, the first heating wire 450 is heated.

When the first heating wire 450 is heated, a user moves the vinyl bag 480 or the air suction pump in a horizontal direction, and thus, the opening 481 of the vinyl bag 480 disposed between the first heating wire 450 and the pressurization rubber 415 is heat-sutured.

In this case, a section heat-sutured by the first heating wire 450 forms an open hole 484 in which a certain section in the opening 481 is opened without the opening 481 of the vinyl bag 480 being overall opened.

In the vinyl bag 480 in which the first heat sealing operation is completed, as illustrated in FIG. 60, a first heat suture line 483 with the open hole 484 formed therein is formed.

Subsequently, the vinyl bag 480 is taken out from a gap between the base member 410 and the housing 430, and then, the vinyl bag 480 is rotated and again inserted between the base member 410 and the housing 430.

FIG. 61 is a sectional view illustrating a state of performing an air discharge operation that performs pumping by inserting the vinyl bag 480 into the air suction pump according to the tenth embodiment of the present invention. FIG. 62 is a plan view schematically illustrating the positions of the stopper projection 470, first heating wire 450, and vinyl bag 480 in the illustrated state of FIG. 61.

In this case, as illustrated in FIG. 62, the vinyl bag 480 is rotated and inserted.

That is, while the vinyl bag 480 is disposed under the first heating wire 450, a vertex in which the opening 481 and side junction portion 482 of the vinyl bag 480 join is inserted into a separated space between the first and second stopper projections 471 and 472.

Subsequently, the vinyl bag 480 is inserted between the first and second stopper projections 471 and 472, and then the opening 481 and side junction portion 482 of the vinyl bag 480 respectively contact the contact surface of the first stopper projection 471 and the contact surface of the second stopper projection 472, whereupon the vinyl bag 480 is no longer inserted.

In this case, the open hole 484 formed in the first heat sealing operation is disposed inside the main gasket 420, and a discharge portion of the vinyl bag 480 through the open hole 484 is disposed on the drop hole 414.

Furthermore, the first heating wire 450 is disposed on the first heat suture line 483 and the side junction portion 482.

Subsequently, by dropping the housing 430, the upper main gasket 421 and the lower main gasket 422 contact each other, thereby preventing air influx/outflux between the inside and outside of each of the main gasket 420.

As the housing 430 descends, the upper block gasket 423 strongly contacts the lower block gasket 424 with the vinyl bag 480 therebetween, and thus, a connection path between the suction hole 432 and first heating wire discharge hole 434 is blocked inside the main gasket 420.

Subsequently, the user lifts the piston member 440.

As the piston member 440 ascends, the internal volume of the housing 430 disposed under the piston part 441 increases, and thus, the check value 433 ascends in an upward direction, thereby opening the suction hole 432. Therefore, the internal air of the vinyl bag 480 fluxes into the housing 430 through the open hole 484 and the suction hole 432.

At this point, the internal air of the vinyl bag 480 is discharged, and simultaneously liquid or powder may be discharged together. Such a material is loaded in the receiving part 412 through the drop hole 414 formed under the open hole 484, and thus, the material and air cannot flux into the housing 430.

When the piston member 440 ascends and then descends, the check valve 433 descends by an air pressure to close the suction hole 432, and, air disposed under the piston part 441 passes through an upper portion of the housing 430 and is discharged to the outside through a gap between the piston part 441 and the rubber ring 448 mounted on an outer circumference surface of the piston part 441.

Furthermore, when the piston member 440 descends, air disposed under the housing 430 may move in a downward direction through the first heating wire discharge hole 434, but, since the first heating wire discharge hole 434 is disposed inside the main gasket 420 and thus blocked from the outside, the air disposed under the housing 430 cannot move to the other place when the piston member 440 descends, and is discharged to the outside through an upper portion of the housing 430 as described above.

By the vertical reciprocating motion of the piston member 440, an air discharge operation that discharges the internal air of the vinyl bag 480 to the outside is performed.

When it is determined that vacuum has been applied to the inside of the vinyl bag 480 by the pumping motion of the piston member 440, as illustrated in FIG. 63, the piston member 440 is pressed and dropped.

Especially, even up to this point, the housing 430 needs to maintain a dropped state.

FIG. 63 is a sectional view illustrating a state of performing a second heat sealing operation that heat-sutures the open hole 484 of the vinyl bag 480 by using the first heating wire 450 of the air suction pump according to the tenth embodiment of the present invention.

As illustrated in FIG. 63, as the piston member 440 descends, the heating wire 450 again contacts the vinyl bag 480.

However, since the first heating wire 450 is not yet connected to the power supply part 460, the first heating wire 450 is not heated.

In this case, since the first heating wire 450 is disposed on the first heat suture line 483 and the side junction portion 482, when the first heating wire 450 is heated, the first heat suture line 483 and the side junction portion 482 are connected by a second heat suture line 485 formed by the first heating wire 450, thereby heat-suturing and closing the open hole 484.

The second heat suturing operation is completed, and thus, the sealed vinyl bag 480 is as illustrated in FIG. 64.

That is, the vinyl bag 480 is sealed using the two heat suture lines 483 and 485 that are formed to be inclined.

As illustrated in FIGS. 67 to 75, the air suction pump of the present invention includes a base member 510, a housing 520, a first heating wire 530, a main gasket 540, a stopper 550, a piston member 560, a power supply part 570, and a sealing part 580.

The base member 510 includes a receiving part 512 that is opened in an upward direction and receives a foreign material discharged from a vinyl bag 590, a support (not shown) in which a top of the support is opened and the receiving part 512 is formed inside the support, and a cover member 513 that is attachably/detachably coupled to a top of the receiving part 512.

According to the eleventh embodiment, the receiving part 512 and the support may be separately formed, or may be formed as one body.

The receiving part 512 is opened in an upward direction. When the piston member 560 moves upward and downward in a state in which the vinyl bag 590 has been disposed through the opened front between the base member 510 and the housing 520, a foreign material discharged from the vinyl bag 590 is placed in the receiving part 512.

The support becomes progressively broader in a downward direction, and thus is stably disposed at a bottom. As illustrated in FIG. 67, the support acts as a buttress that stably supports the air suction pump of the present invention overall.

The cover member 513 covers a top of the receiving part 512.

When the cover member 513 is disposed to cover the top of the receiving part 512, a contact portion of the cover member 513 and receiving part 512 blocks the influx and outflux of air through a separate sealing means.

A suction hole 514 and a discharge hole 515, which connect the receiving part 512 and the outside, are formed in the cover member 513.

The suction hole 514 and the discharge hole 515 are separated from each other, and a lower block gasket 518 is mounted around the suction hole 515. Thus, as described below, when the piston member 560 descends, the lower block gasket 518 blocks a connection path between the suction hole 514 and the discharge hole 515.

The housing 520 is formed in a hollow cylinder shape whose a top and a bottom are opened, and disposed to be movable in a vertical direction, on the base member 510.

The housing 520 includes a housing body 521, a lower cover 522, and a punch projection 528.

The housing body 521 is formed in a hollow cylinder shape whose a top and a bottom are opened, and a lower portion of the piston member 560 is disposed inside the housing body 521.

The lower cover 522 is mounted on a bottom of the housing body 521, and covers the bottom of the housing body 521.

The lower cover 522 includes a lower supporting part 523, a pressurization part 524, a first spring 525, and a connection terminal 529.

The lower supporting part 523 is mounted on the bottom of the housing body 521, and a lower main gasket 541 having a hollow closed curve is mounted on a bottom of the lower supporting part 523. A check valve 523 a, which is opened only when air fluxes in a direction from a lower portion to an upper portion, is mounted on the lower supporting part 523.

A generally known check valve may be used as the check valve 523 a, and thus, its detailed structural description is not provided.

A first guide projection 526 is downwardly protrusion-formed at the lower supporting part 523, and a guide groove 516 into which the first guide projection 526 is inserted is formed in the base member 510. A first elastic member 527 is mounted on the first guide projection 526.

Therefore, with the housing 520 being upwardly separated from the base member 510, the housing 520 is elastic-supported, and is mounted to be movable in a vertical direction.

The pressurization part 524 passes through the lower supporting part 523 and ascends, and the punch projection 528 and the heating wire 530 are disposed under the pressurization part 524.

The first spring 525 is disposed between the lower support 523 and a top of the pressurization part 524, and elastic-supports the pressurization part 524 in an upward direction with respect to the lower supporting part 523.

The connection terminal 529 is mounted on the lower cover 522, and a bottom of the connection terminal 529 is connected to the first heating wire 530.

The punch projection 528 is mounted on a bottom of the lower cover 522 to protrude in a downward direction. When the housing 520 descends, the punch projection 528 cuts a vinyl bag 590 disposed between the base member 510 and the housing 520.

Moreover, when the housing 520 descends, the punch projection 528 cuts the vinyl bag 590, and then, the suction hole 514 formed in the base member 510 is inserted into the vinyl bag 590.

The punch projection 528 includes first and second punch projections 528 a and 528 b which are formed in a triangular shape and of which a vertex portion is disposed downwardly.

The first and second punch projections 528 a and 528 b are separated from each other in parallel.

Moreover, a gap between the first and second punch projections 528 a and 528 b becomes narrower progressively closer to the front, namely, progressively in a direction in which the vinyl bag 590 is inserted, thus facilitating the easy cutting of the vinyl bag 590.

Moreover, depending on the case, the vertex portion of the first punch projection 528 a and the vertex portion of the second punch projection 528 b are disposed across, in which case the first and second punch projections 528 a and 528 b may act as scissors to cut the vinyl bag 590 disposed thereunder.

The first heating wire 530 surrounds the punch projection 528 and is mounted to be exposed to the outside, on a bottom of the lower cover 522, and specifically, a bottom of the pressurization part 524.

In the eleventh embodiment of the present invention, the first heating wire 530 is formed in a U-shape that surrounds the punch projection 528.

When the housing 520 descends, the first heating wire 530 contacts the lower block gasket 518.

The main gasket 540 is mounted on a top of the base member 510 to protrude in an upward direction, and/or mounted on a bottom of the housing 520 to protrude in a downward direction.

In the eleventh embodiment of the present invention, the main gasket 540 is mounted on the top of the base member 510 and the bottom of the housing 520, but, depending on the case, the main gasket 540 may be mounted on only one of the top of the base member 510 and the bottom of the housing 520.

In the eleventh embodiment of the present invention, the main gasket 540 includes a closed shape of upper main gasket 542 that is downwardly protrusion-mounted on the bottom of the housing 520 and specifically an outer portion of the lower supporting part 523, and a closed shape of lower main gasket 541 that is upwardly protrusion-mounted on the top of the base member 510 and specifically an outer portion of the cover member 513 and, when the housing 520 descends, contacts the upper main gasket 542.

When the housing 520 descends, the upper main gasket 542 and the lower main gasket 541 contact each other and are compressed.

The punch projection 528, the first heating wire 530, the suction hole 514, and the discharge hole 515 are all disposed inside the main gasket 540.

When the housing 520 descends, the stopper 550 allows the housing 520 to be dropped by a certain length.

To this end, the stopper 520 is mounted on the top of the base member 510 to protrude in an upward direction, and/or mounted on the bottom of the housing 520 to protrude in a downward direction.

In the eleventh embodiment of the present invention, the stopper 550 is formed at the lower supporting part 523 and the cover member 513.

In more detail, the stopper 550 includes a lower stopper 551 that is upwardly protrusion-formed on the cover member 513 with the lower main gasket 541 mounted thereon, and an upper stopper 552 that is downwardly protrusion-formed on the lower supporting part 523 with the upper main gasket 542 mounted thereon.

The sum of protrusion lengths of the lower stopper 551 and upper stopper 552 is less than a protrusion length of the main gasket 540.

Therefore, when the housing 520 descends, the upper main gasket 542 and the lower main gasket 541 first contact each other, and then, the lower stopper 551 and upper stopper 552 contact each other.

Thus, when the housing 520 descends, the upper main gasket 542 and the lower main gasket 541 press and compress the vinyl bag 590 disposed between the base member 510 and the housing 520 until the lower stopper 551 and upper stopper 552 contact each other and thus the drop of the housing 520 is stopped.

If there is no stopper 550, when the housing 520 descends, the vinyl bag 590 disposed between the upper main gasket 542 and the lower main gasket 541 is too much pressed, and thus, an error can occur while the internal air of the vinyl bag 590 passes through a gap between the upper main gasket 542 and the lower main gasket 541 and moves to a portion cut by the punch projection 528.

However, according to the present invention, by mounting the stopper 550 that allows the housing 520 to descend by a certain length, the vinyl bag 590 disposed between the upper main gasket 542 and the lower main gasket 541 is prevented from being too much pressed when the housing 520 descends, and thus, the internal air of the vinyl bag 590 passes through the gap between the upper main gasket 542 and the lower main gasket 541 and moves to a portion cut by the punch projection 528 well.

In the present invention, the stopper 550 is formed at an outer portion of the cover member 513 and an outer portion of the lower supporting part 523, but, the stopper 550 may be formed inside the cover member 513 and/or inside the lower supporting part 523.

The piston member 560 is disposed to be movable upward and downward, inside the housing 520, and an upper portion of the piston member 560 passes through the top and is exposed to the outside.

The piston member 560 includes a piston part 561, a load part 562, and a handle part 563.

The piston part 561 has the same shape as that of an inner surface of the housing 520, and a rubber ring 561 a is mounted on an outer circumference surface of the piston part 561 and contacts the inner surface of the housing body 521.

The load part 562 is formed in a rod shape, and coupled to a top of the piston part 561. The power supply part 570 is inserted into and disposed inside the load part 562.

To mount the piston member 560 inside the housing 520, the load part 562 and the piston member 560 may be separately manufactured and assembled.

The handle part 563 is formed to be exposed to the outside, on the load part 562.

That is, the handle part 563 is disposed on the housing body 521.

Furthermore, a button part 564 that is elastic-supported to be lifted or dropped by the second spring 565 is protrusion-mounted between the a bottom of the handle part 563 and a top of the housing body 521.

By ascending or descending, the button part 564 electrically connects or disconnects the power supply part 570 and the first heating wire 530.

To this end, the button part 564 is electrically connected to the power supply part 570 and a connection terminal 529 through respective electrical lines.

More specifically, the button part 564 and the power supply part 570 are connected by an electrical line (not shown), and the button part 564 and the connection terminal 529 are connected by an electrical line (not shown). Thus, when the button part 564 is pushed and maximally compresses the second spring 565, the electrical line connected to the power supply part 570 is connected to the electrical line connected to the connection terminal 529.

An electrical line 529 a connected to the connection terminal 529 passes through the piston member 560 and is connected to the button part 564.

In FIG. 71, a portion of the electrical line 529 a connected to the connection terminal 529 is illustrated.

More details on this can be sufficiently understood with reference to a known button type switch of the related art.

Through the above-described configuration, when the button part 564 is not pushed, and the power supply part 570 and the first heating wire 530 are not connected, but, when the button part 564 is pushed, and the power supply part 570 and the first heating wire 530 are connected.

In the eleventh embodiment of the present invention, the second spring 565 and the button part 564 are mounted under the handle part 563, but may be mounted on the housing body 521.

Furthermore, the bottom of the handle part 563 and the top of the housing body 521 are separated from each other by the button part 564.

That is, before the bottom of the handle part 563 contacts the top of the housing body 521, the button part 564 first contacts the top of the housing body 521. When an external force that downwardly moves the piston member 560 is applied, the bottom of the handle part 563 and the top of the housing body 521 are separated from each other by the button part 564 that is elastic-supported downwardly by the second spring 565.

When an external force that downwardly moves the piston member 560 is not applied, namely, before the second spring 565 is compressed, the power supply part 570 and the connection terminal 529 are electrically disconnected by the button part 564.

Then, when the piston member 560 is dropped, the button part 564 is pushed and thus the second spring 565 is compressed, whereupon the power supply part 570 and the connection terminal 529 are electrically connected by the button part 564.

The power supply part 570 supplies power to the first heating wire 564, and is mounted inside the load part 562.

Furthermore, the power supply part 570 is selectively connected to the first heating wire 530 through the button part 564 and the connection terminal 529.

When the power supply part 570 and the connection terminal 529 are electrically connected through the button part 564 by the drop of the piston member 560, the power supply part 570 and the first heating wire 530 are connected, and power is supplied to the first heating wire 530, thereby heating the first heating wire 530.

In this case, when the button part 564 is maximally pushed, the power supply part 570 and the first heating wire 530 are connected.

Furthermore, when the piston member 560 descends, the bottom of the piston member 560 (i.e., the piston part 561) presses the top of the pressurization part 524 to compress the first spring 525, thereby dropping the pressurization part 524.

The sealing part 580 is mounted on the piston member 560 in a direction opposite to the base member 510.

The sealing part 580 heat-sutures an opening 591 of the vinyl bag 590, and may configure one element of the air suction apparatus of the present invention. Alternatively, the sealing part 580 may be implemented as a separate product, namely, a sealing apparatus.

The sealing part 580 includes a sealing body 581, a sealing cover 582, a second heating wire 583, a pressurization roller part 584, and a third spring 587.

The sealing body 581 is mounted on the piston member 560.

The sealing cover is mounted on the sealing body 581 to be movable in a vertical direction.

To this end, a second guide projection 582 a is downwardly protrusion-formed at the sealing cover 582, and a second elastic member 582 b is mounted on the second guide projection 582 a. The second guide projection 582 a is mounted to pass through the sealing body 581.

Therefore, the sealing cover 582 is mounted to be movable in a vertical direction, with the sealing cover 582 being separated from the sealing body 581 by the elastic force of the second elastic member 582 b.

In the eleventh embodiment, the sealing cover 582 is divided into a first cover 588 and a second cover 589.

The second guide projection 582 a is formed under the first cover 588, and supported and mounted between the pressurization roller part 584 and the first and second covers 588 and 589.

The second heating wire 583 is connected to the power supply part 570, and mounted on the sealing body 581 to be exposed in an upward direction.

When the sealing cover 582 does not descend, the second heating wire 583 is disconnected from the power supply part 570. When the sealing cover 582 descends, the second heating wire 583 is pressurized and connected to the power supply part 570.

Such a structure may use a known structure of the related art, and thus, its detailed description is not provided.

The pressurization roller part 584 includes a roller body 585 that is mounted on the sealing cover 582 to be movable in a vertical direction, and two or more rollers 586 that are mounted on the roller body 585 to rotate in a direction in which the second heating wire 583 is disposed.

In the eleventh embodiment of the present invention, the roller 586 is provided as two, and the two rollers 586 are separated from each other.

The third spring 587 is implemented as a coil spring. The third spring 587 is disposed between a bottom of the sealing cover 582 and a top of the roller body 585, and elastic-supports the pressurization part 584 in a vertical direction.

With the vinyl bag 590 being disposed between the sealing cover 582 and the second heating wire 583, while the sealing cover 582 moves toward the second heating wire 583 by the third spring 587, when an external force that moves the sealing cover 582 is too strong, the pressurization roller part 584 moves vertically while compressing the third spring 587, and the roller 586 pressurizes the vinyl bag 590 in the second heating wire 583 direction by the springback force of the third spring 587.

In the eleventh embodiment of the present invention, the sealing part 580 is described as one element of the air suction apparatus, but only the sealing part 580 may be implemented as a separate product, namely, a sealing apparatus.

When the sealing part 580 is implemented as a separate product (i.e., a sealing apparatus), the power supply part 570 is mounted inside the sealing body 581.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 76 is a sectional view illustrating a state that heat-sutures an opening by inserting the vinyl bag 590 into the sealing part 580 of the air suction pump according to the eleventh embodiment of the present invention. FIG. 77 is a perspective view illustrating a state in which the vinyl bag 590 has been inserted between the base member 510 and the housing 520 of the air suction pump according to the eleventh embodiment of the present invention. FIG. 78 is a sectional view in the illustrated of FIG. 77. FIG. 79 is a sectional view illustrating a state that cuts the vinyl bag 590 by dropping the housing 520 in FIG. 78. FIG. 80 is a sectional view illustrating a state that performs pumping by lifting the piston member 560 in the illustrated state of FIG. 79. FIG. 81 is a sectional view illustrating a state that heat-sutures a cut portion 595 of the vinyl bag 590 after completing the application of vacuum in the illustrated state of FIG. 80. FIG. 82 is a perspective view illustrating the vinyl bag 590 when the application of vacuum is completed by the air suction pump according to the eleventh embodiment of the present invention.

In a state that is as illustrated in FIG. 67, by turning over the air suction pump except the support, as illustrated in FIG. 76, the sealing part 580 is disposed at the support.

In this state, the opening 591 of the vinyl bag 590 is inserted into the sealing part 580, and then, by pressing in a downward direction, the opening 591 of the vinyl bag 590 is heat-sutured by the second heating wire 583.

In more detail, the opening 591 of the vinyl bag 590 is inserted between the sealing cover 582 and the sealing body 581.

Subsequently, by pressing the piston member 560, the second heating wire 583 and the roller 586 join with the vinyl bag 590 therebetween.

However, up to this point, the second heating wire 583 is disconnected from the power supply part 570.

By further pressing the piston member 560, the second heating wire 583 is connected to the power supply part 570, and the second heating wire 583 is heated by a current supplied from the power supply part 570.

In this case, the second heating wire 583 joins the roller 586 with the vinyl bag 590 therebetween, and pressurizes the vinyl bag 590.

In this state, by pulling the vinyl bag 590 in a side direction of an insertion direction, the roller 586 rotates to transfer the vinyl bag 590, and the opening 591 of the vinyl bag 590 is heat-sutured by the second heating wire 583 and the roller 586.

In this case, the vinyl bag 590 is well transferred without being one-sided or torn by a plurality of the rollers 586.

Moreover, the second heating wire 583 joins at least two or more of the plurality of rollers 586, and thus, the vinyl bag 590 has two or more heat-sutured portions. Accordingly, heat suturing can be accurately performed.

In addition, when the vinyl bag 590 is thick or a force that presses the piston member 560 is strong, the pressurization roller part 584 compresses and moves the third spring 587, and thus, the vinyl bag 590 is stably disposed and transferred between the roller 586 and the second heating wire 583.

In FIG. 82, the heat-sutured portion is illustrated as a first heat suture portion 593.

Subsequently, by again turning over the air suction pump, the air suction pump returns to the illustrated state of FIGS. 77 and 78.

The vinyl bag 590 with the heat-sutured opening 591, as illustrated in FIGS. 77 and 78, is insertion-disposed through the opened front between the base member 510 and the housing 520.

In this case, as illustrated in FIG. 77, the vinyl bag 370 enables a side junction portion 592 to be insertion-disposed through the opened front between the base member 510 and the housing 520.

The housing 520 is separated from the cover member 513 by the first elastic member 527, and thus, the vinyl bag 590 is inserted into and disposed in a separation space formed between the housing 520 and the cover member 513.

In this case, as illustrated in FIG. 78, the vinyl bag 590 covers the suction hole 514, and is disposed under the punch projection 528.

Moreover, in the illustrated state of FIG. 48, the bottom of the handle part 563 is separated from the top of the housing body 521 by the second spring 565 and the button part 564, and the power supply part 570 and the connection terminal 529 are not connected by the button part 564, in which case the first heating wire 530 is not heated.

In this state, as illustrated in FIG. 79, the housing 520 is dropped.

At this point, since the housing 520 descends, the piston member 560 and the sealing part 580 descend automatically.

As the housing 520 descends, the punch projection 528 cuts the vinyl bag 590, and then, the suction hole 514 is inserted into the vinyl bag 590.

Furthermore, as the housing 520 descends, the upper main gasket 542 and the lower main gasket 541 contact each other, thereby preventing air influx/outflux between the inside and outside of each of the main gasket 540 and performing compression.

Then, when the upper stopper 552 and the lower stopper 551 contact, the housing 520 cannot descend any longer.

Therefore, the prevent invention can prevent that the vinyl bag 590 disposed between the upper main gasket 542 and the lower main gasket 541 is too much compressed, and thus, the internal air of the vinyl bag 590 cannot move to the cut portion 595 of the vinyl bag 590 cut by the punch projection 528.

Subsequently, as illustrated in FIG. 80, a user lifts the piston member 560.

As the piston member 560 ascends, the internal volume of the housing body 521 disposed under the piston part 561 increases, and thus, the check value 523 a is opened by a pressure difference between an upper portion and lower portion thereof, and air disposed under the lower supporting part 523 moves into the housing body 521 through the check valve 523 a.

Furthermore, the internal air of the vinyl bag 590 moves to the suction hole 514 through a portion cut by the punch projection 528, again moves to the discharge hole 515 through the receiving part 512, and again moves into the housing body 521 through the check valve 523 a.

At this point, the internal air of the vinyl bag 590 is discharged, and simultaneously liquid or powder may be discharged together. Such a material moves to the receiving part 512 through the suction hole 514 and is dropped and loaded in the receiving part 512, and thus, the material and air cannot flux into the housing 520.

When the piston member 560 ascends and then descends, air disposed under the piston part 561 passes through an upper portion of the housing 520 and is discharged to the outside through a gap between the piston part 561 and the rubber ring 561 a mounted on an outer circumference surface of the piston part 561.

Furthermore, the check valve 523 a is closed, and prevents the internal air of the housing body 521 from moving to under the lower cover 522.

By the vertical reciprocating motion of the piston member 560, the internal air of the vinyl bag 590 is continuously discharged to the outside.

When it is determined that vacuum has been applied to the inside of the vinyl bag 590 by the pumping motion of the piston member 440, the piston member 560 is pressed and dropped.

Especially, even up to this point, the housing 520 needs to maintain a dropped state.

As illustrated in FIG. 81, as the piston member 560 descends, the button part 564 contacts the top of the housing body 521, and the second spring 565 is compressed.

Therefore, the power supply part 570 and the connection terminal 529 are connected through the button part 564.

Accordingly, the power supply part 570 and the first heating wire 530 are connected, and thus, the first heating wire 530 is heated.

In this case, when the button part 564 is slightly pushed, the power supply part 570 and the first heating wire 530 are not connected, but, when the button part 564 is sufficiently pushed, the power supply part 570 and the first heating wire 530 are connected. Therefore, when the piston member 560 ascends and descends, the first heating wire 530 is not unnecessarily heated.

Furthermore, as the piston member 560 further descends, the bottom of the piston part 561 joins the top of the pressurization part 524, and thus, the first spring 525 is compressed, thereby dropping the pressurization part 524.

As the pressurization part 524 descends, the first heating wire 530 is connected to and heated by the power supply part 570, and the heated first heating wire 530 also descends. Therefore, the first heating wire 530 strongly presses the top of the vinyl bag 590.

As the heated first heating wire 530 strongly presses the top of the vinyl bag 590, by heating the first heating wire 530, as illustrated in FIG. 82, the second heat suture portion 594 is formed around the cut portion 595 of the vinyl bag 590 cut by the punch projection 528.

At this point, since the first heating wire 530 is disposed to surround the punch projection 528, the cut portion 595 of the vinyl bag 590 is blocked from the inside of the vinyl bag 590 by the second heat suture portion 594.

Furthermore, as illustrated in FIG. 82, the second heat suture portion 594 is connected to the side junction portion 592 of the vinyl bag 590 by the first heating wire 530.

After the vacuum applying and heat suturing of the vinyl bag 590 are completed, the receiving part 512 is separated from the support and cleaned.

FIG. 95 is a perspective view illustrating the vinyl bag when the application of vacuum is completed by the air suction pump according to the twelfth embodiment of the present invention. FIG. 96 is a perspective view illustrating an air suction pump according to another twelfth embodiment of the present invention.

The air suction pump of the present invention includes a base member 610, a housing 620, a first heating wire 630, a piston member 660, a power supply part 670, and a main gasket 640.

The base member 610 includes a receiving part 612 that is opened in an upward direction and receives a foreign material discharged from a vinyl bag 690, a support (not shown) in which a top of the support is opened and the receiving part 612 is formed inside the support, and a cover member 613 that is attachably/detachably coupled to a top of the receiving part 612.

The receiving part 612 is opened in an upward direction. When the piston member 660 moves upward and downward in a state in which the vinyl bag 690 has been disposed through the opened front between the base member 610 and the housing 620, a foreign material discharged from the vinyl bag 690 is placed in the receiving part 612.

A first connection hole 612 a, which connects the inside and outside of the receiving part 612, is formed under the receiving part 612. A connection door, which opens or closes the first connection hole 612 a, is mounted on the receiving part 612.

The first connection hole 612 a may be formed to be height-stepped in a plurality of steps.

The cover member 613 covers a top of the receiving part 612.

When the cover member 613 is disposed to cover the top of the receiving part 612, a contact portion of the cover member 613 and receiving part 612 blocks the influx and outflux of air through a separate sealing means.

A suction hole 614 and a flux hole 615, which connect the receiving part 612 and the outside, are formed in the cover member 613.

The suction hole 614 and the flux hole 615 are separated from each other, and a lower block gasket 618 is mounted around the suction hole 615. Thus, as described below, when the piston member 660 descends, the lower block gasket 618 blocks a connection path between the suction hole 614 and the flux hole 615.

A punch projection 629 formed under the housing 620, as described below, is inserted into the drop hole 614 when the housing 620 descends.

The housing 620 is formed in a hollow cylinder shape whose a top and a bottom are opened, and disposed to be movable in a vertical direction, on the base member 610.

The housing 620 includes a housing body 621, a lower cover 622, a pressurization part 623, a check valve 624, a elastic part 625, and an intermediate plate 626.

The housing body 621 is formed in a hollow cylinder shape whose a top and a bottom are opened, and a lower portion of the piston member 660 is disposed inside the housing body 621.

The lower cover 622 is mounted on a bottom of the housing body 621, and covers the bottom of the housing body 621.

A mounting hole 622 b, passing through a top and a bottom of the lower cover 622, is formed inside the lower cover 622.

A lower main gasket 641 having a hollow closed curve shape is formed to protrude in a downward direction, under the lower cover 622.

Furthermore, a guide projection 627 is downwardly protrusion-formed at the lower cover 622, a guide groove 616 into which the guide projection 627 is inserted is formed in the base member 610, and a second spring 627 a is mounted on the guide projection 627.

Therefore, the housing 620 is elastic-supported, with the housing 620 being separated in an upward direction with respect to the base member 610, and mounted to be movable in a vertical direction.

The pressurization part 623 is inserted into and disposed in the mounting hole 622 b, and a suction hole 623 a is through-formed in the pressurization part 623 in a vertical direction. The first heating wire 630 surrounding the suction hole 623 a is mounted on a bottom of the pressurization part 623.

An upper block gasket 628, which contacts the lower block gasket 618 when the pressurization part 623 descends, is mounted on the bottom of the pressurization part 623. The bottom of the pressurization part 623 is opened in the rearward direction of the pressurization part 623 by the upper block gasket 628.

The check valve 624 is mounted on the suction hole 623 a, and opens or closes a top of the suction hole 623 a.

The check valve 624 opens the top of the suction hole 623 a when the piston member ascends, and closes the top of the suction hole 623 a when the piston member descends.

The punch projection 629, which cuts the vinyl bag 690 disposed between the pressurization part 623 and the base member 610 when the housing 620 descends, is mounted on the bottom of the pressurization part 623 to protrude in a downward direction.

When the housing 620 descends, the punch projection 629 cuts the vinyl bag 629, and then is inserted into the drop hole 614 formed in the base member 610.

The elastic part 625 is mounted on a top of the lower cover 622, and the pressurization part 623 is coupled to a bottom of the elastic part 625.

The elastic part 625 is formed of a rubber material. In a free state, the elastic part 625 is protrusion-formed to be convex in the piston member 660 direction, namely, in an upward direction. When the piston member 660 descends, the elastic part 625 is pressed and compressed by the piston member 660, thereby dropping the pressurization part 623.

A second connection hole 625 a, connected to the suction hole 623 a by the check valve 624, is formed in the elastic part 625.

A pressing part 625 b, which presses the check valve 624 by the second connection hole 625 a, is protrusion-formed at the elastic part 625.

The pressing part 625 b may be elastic-deformed in a vertical direction, and thus, when the check valve 624 moves in a vertical direction and opens or closes the suction hole 623 a, the pressing part 625 b and the check valve 624 are bent in a vertical direction.

Since the pressing part 625 b is pressing the check valve 624, the pressing part 625 b prevents that the check valve 624 arbitrarily ascends and thus the suction hole 623 a is opened, and enables the check valve 624 to more easily open or close the top of the suction hole 623 a.

The intermediate plate 626 is disposed on the elastic part 625, and coupled to the pressurization part 623 disposed under the elastic part 625.

That is, the elastic part 625 is disposed between the elastic part 625 and the pressurization part 623, and the intermediate plate 626 and the pressurization part 623 are coupled through the elastic part 625.

Therefore, the intermediate plate 626, the elastic part 625, and the pressurization part 623 move upward and downward together.

Furthermore, a connection terminal 626 a is mounted on the intermediate plate 626 to be exposed in an upward direction, and, as described below, when the piston member 660 descends, the intermediate plate contacts the power supply part 670.

The connection terminal 626 a is connected to the first heating wire 630, coupled to the bottom of the pressurization part 623, by a connection line passing through the pressurization part 623.

Therefore, when the piston member 660 descends, the power supply part 670 contacts the connection terminal 626 a, and thus, the first heating wire 630 is heated by a current supplied from the power supply part 670.

The first heating wire 630 surrounds the punch projection 629 and is mounted on a bottom of the lower cover 622 to be exposed to the outside.

In the twelfth embodiment of the present invention, the first heating wire 630 is formed in a U-shape that surrounds the punch projection 629.

When the housing 620 descends, the first heating wire 630 contacts the lower block gasket 618.

The main gasket 640 is mounted on a top of the base member 610 to protrude in an upward direction, and/or mounted on a bottom of the housing 620 to protrude in a downward direction.

In the twelfth embodiment of the present invention, the main gasket 640 is mounted on the top of the base member 610 and the bottom of the housing 620, but, depending on the case, the main gasket 640 may be mounted on only one of the top of the base member 610 and the bottom of the housing 620.

In the twelfth embodiment of the present invention, the main gasket 640 includes a closed shape of upper main gasket 642 that is downwardly protrusion-mounted on the bottom of the housing 620 and specifically an outer portion of the lower cover 622, and a closed shape of lower main gasket 641 that is upwardly protrusion-mounted on the top of the base member 610 and specifically an outer portion of the cover member 613 and, when the housing 620 descends, contacts the upper main gasket 642.

When the housing 620 descends, the upper main gasket 642 and the lower main gasket 641 contact each other and are compressed, thereby preventing external air from fluxing into a gap between the housing 620 and the base member 610.

The punch projection 629, the first heating wire 630, the drop hole 614, and the flux hole 615 are all disposed inside the main gasket 640.

The lower stopper 613 a is upwardly protrusion-formed at the cover member 613, and the upper stopper 622 a is downwardly protrusion-formed at the lower cover 622.

The sum of protrusion lengths of the lower stopper 613 a and upper stopper 622 a is less than a protrusion length of the main gasket 640.

Therefore, when the housing 620 descends, the upper main gasket 642 and the lower main gasket 641 join first, and then, the upper stopper 622 a and the lower stopper 613 a contact each other.

Thus, when the housing 620 descends, the upper main gasket 642 and the lower main gasket 641 respectively contact the upper stopper 622 a and the lower stopper 613 a, and presses and compresses the vinyl bag 690 disposed between the base member 610 and the housing 620 until the drop of the housing 620 is stopped.

The piston member 660 is disposed inside the housing 620 to be movable upward and downward, and the top of the piston member 660 passes through the top of the housing 620 and is exposed to the outside.

The piston member 660 includes a piston part 661, a load part 662, and a handle part 663.

The piston part 661 has the same shape as that of an inner surface of the housing 620, and a rubber ring 661 a is mounted on an outer circumference surface of the piston part 661 and contacts the inner surface of the housing body 621. A connection terminal 661 b connected to the power supply part 670 is protrusion-formed at the bottom of the piston part 661.

The load part 662 is formed in a rod shape, and coupled to a top of the piston part 661. The power supply part 670 is inserted into and disposed inside the load part 662.

To mount the piston member 660 inside the housing 620, the load part 662 and the piston member 660 may be separately manufactured and assembled.

The handle part 663 is formed on the load part 662 to be exposed to the outside.

That is, the handle part 663 is disposed on the housing body 621.

Furthermore, a button part 664 that is elastic-supported to be lifted or dropped by the second spring 665 is protrusion-mounted between the a bottom of the handle part 663 and a top of the housing body 621.

By ascending or descending, the button part 664 electrically connects or disconnects the power supply part 670 and the first heating wire 630.

To this end, the button part 664 is electrically connected to the power supply part 670 and a connection terminal 629 through respective electrical lines.

More specifically, the button part 664 and the power supply part 670 are connected by an electrical line (not shown), and the button part 664 and the connection terminal 661 b are connected by an electrical line (not shown). Thus, when the button part 664 is pushed and maximally compresses the second spring 665, the electrical line connected to the power supply part 670 is connected to the electrical line connected to the connection terminal 661 b.

An electrical line connected to the connection terminal 661 b passes through the piston member 660 and is connected to the button part 664.

More details on this can be sufficiently understood with reference to a known button type switch of the related art.

Through the above-described configuration, when the button part 664 is not pushed, and the power supply part 670 and the first heating wire 630 are not connected, but, when the button part 664 is pushed, and the power supply part 670 and the first heating wire 630 are connected.

In the eleventh embodiment of the present invention, the second spring 665 and the button part 664 are mounted under the handle part 663, but may be mounted on the housing body 621.

Furthermore, the bottom of the handle part 663 and the top of the housing body 621 are separated from each other by the button part 664.

That is, before the bottom of the handle part 663 contacts the top of the housing body 621, the button part 664 first contacts the top of the housing body 621. When an external force that downwardly moves the piston member 660 is applied, the bottom of the handle part 663 and the top of the housing body 621 are separated from each other by the button part 664 that is elastic-supported downwardly by the first spring 665.

When an external force that downwardly moves the piston member 660 is not applied, namely, before the first spring 665 is compressed, the power supply part 670 and the connection terminal 661 b are electrically disconnected by the button part 664.

Then, when the piston member 660 is dropped, the button part 664 is pushed and thus the first spring 665 is compressed, whereupon the power supply part 670 and the connection terminal 661 b are electrically connected by the button part 664.

The power supply part 670 supplies power to the first heating wire 664, and is mounted inside the load part 662.

Furthermore, the power supply part 670 is selectively connected to the first heating wire 630 through the button part 664 and the connection terminal 661 b.

When the power supply part 670 and the connection terminal 661 b are electrically connected and the connection terminal 661 b and the connection terminal 626 a are connected through the button part 664 by the drop of the piston member 660, the power supply part 670 and the first heating wire 630 are connected, and power is supplied to the first heating wire 630, thereby heating the first heating wire 630.

In this case, when the button part 664 is maximally pushed, the power supply part 670 and the first heating wire 630 are connected.

Furthermore, when the piston member 660 descends, the bottom of the piston member 660 (i.e., the piston part 661) presses the top of the intermediate plate 626 to downwardly compress the elastic part 625, thereby dropping the pressurization part 623.

Furthermore, a rail projection 666 is protrusion-formed on the piston member 660.

The rail projection 666 presses a zipper part 693 in the vinyl bag 690 (in which a generally used zipper bag, namely, the zipper part 693 is formed), thereby allowing a zipper to be well clamped.

Moreover, as illustrated in FIG. 96, a separate pressing cover 680 that ascends or descends in a vertical direction with respect to the piston member 660 may be mounted on the top of the piston member 660.

A rail projection 681 is protrusion-formed at a bottom of the pressing cover 680 and/to the top of the piston member 660.

Therefore, the zipper part 693 of the zipper bag is inserted between the pressing cover 680 and the piston member 660, and, when the rail projections 666 and 681 pressurize the zipper part 693 by pressing the pressing cover 680, by moving the zipper bag or the air suction pump, the zipper part 693 is continuously clamped well.

A rail projection 619 may be formed under the base member 610 as well as the piston member 660.

Hereinafter, an operation of the present invention having the above-described configuration will be described in detail.

FIG. 91 is a sectional view illustrating a state in which the vinyl bag 690 has been inserted between the base member 610 and the housing 620 of the air suction pump according to the twelfth embodiment of the present invention. FIG. 92 is a sectional view illustrating a state that cuts the vinyl bag 690 by dropping the housing in FIG. 91. FIG. 93 is a sectional view illustrating a state that performs pumping by lifting the piston member 660 in FIG. 92. FIG. 94 is a sectional view illustrating a state that heat-sutures a cut portion 695 of the vinyl bag 690 after completing the application of vacuum in the illustrated state of FIG. 93. FIG. 95 is a perspective view illustrating the vinyl bag 690 when the application of vacuum is completed by the air suction pump according to the twelfth embodiment of the present invention. FIG. 96 is a perspective view illustrating an air suction pump according to another twelfth embodiment of the present invention.

When the rail projections 619 and 666 formed at the piston member 660 or the base member 610 have pressurized the zipper 693 formed in an opening 691 of the zipper bag, the air suction pump or the zipper bag is moved.

Then, since the rail projections 619 and 666 are pressing the zipper part 693, the zipper part 693 moves and is clamped.

Therefore, the opening 691 of the vinyl bag 690 (i.e., the zipper bag) with the zipper part 693 formed therein is sealed.

The vinyl bag 690 with the sealed opening 691, as illustrated in FIG. 91, is insertion-disposed through the opened front between the base member 610 and the housing 620.

In this case, the vinyl bag 690 enables a side junction part 692 of FIG. 95 to be insertion-disposed through the opened front between the base member 610 and the housing 620.

The housing 620 is separated from the cover member 613 by the second spring 627 a, and thus, the vinyl bag 690 is insertion-disposed in a separation space between the housing 620 and the cover member 613.

In this case, as illustrated in FIG. 91, the vinyl bag 690 covers the drop hole 614, and is disposed under the punch projection 629.

Moreover, in the illustrated state of FIG. 91, the bottom of the handle part 663 is separated from the top of the housing body 621 by the first spring 665 and the button part 664, and the power supply part 670 and the connection terminal 661 b are not connected by the button part 664, in which case the first heating wire 630 is not heated.

In this state, as illustrated in FIG. 92, the housing 620 is dropped.

As the housing 620 descends, the punch projection 628 cuts the vinyl bag 690, and then, the drop hole 614 is inserted into the vinyl bag 690.

Furthermore, as the housing 620 descends, the upper main gasket 642 and the lower main gasket 641 contact each other, thereby preventing air influx/outflux between the inside and outside of each of the main gasket 640 and performing compression.

Then, when the upper stopper 622 a and the lower stopper 613 a contact each other, the housing 620 cannot descend any longer.

Therefore, the prevent invention can prevent that the vinyl bag 690 disposed between the upper main gasket 642 and the lower main gasket 641 is too much compressed, and thus, the internal air of the vinyl bag 690 cannot move to the cut portion 695 of the vinyl bag 690 cut by the punch projection 629.

Subsequently, as illustrated in FIG. 93, a user lifts the piston member 660.

As the piston member 660 ascends, the internal volume of the housing body 621 disposed under the piston part 661 increases, and thus, the check value 624 is opened by a pressure difference between an upper portion and lower portion thereof, and air disposed under the lower cover 622 moves into the housing body 621 through the suction hole 623 a and the check valve 624.

Furthermore, the internal air of the vinyl bag 690 moves to the drop hole 614 through a portion cut by the punch projection 629, again moves to the flux hole 615 through the receiving part 612, and again moves into the housing body 621 through the suction hole 623 a and the check valve 624.

At this point, the internal air of the vinyl bag 690 is discharged, and simultaneously liquid or powder may be discharged together. Such a material moves to the receiving part 612 through the drop hole 614 and is dropped and loaded in the receiving part 612, and thus, the material and air cannot flux into the housing 620.

When the piston member 660 ascends and then descends, air disposed under the piston part 661 passes through an upper portion of the housing 620 and is discharged to the outside through a gap between the piston part 661 and the rubber ring 661 a mounted on an outer circumference surface of the piston part 661.

Furthermore, the check valve 624 is closed, and prevents the internal air of the housing body 621 from moving to under the lower cover 622.

Moreover, since the check valve 624 is pressed by the pressing part 625 b, the top of the suction hole 623 a is better closed.

By the vertical reciprocating motion of the piston member 660, the internal air of the vinyl bag 690 is continuously discharged to the outside.

When it is determined that vacuum has been applied to the inside of the vinyl bag 690 by the pumping motion of the piston member 660, the piston member 660 is pressed and dropped.

Especially, even up to this point, the housing 620 needs to maintain a dropped state.

As illustrated in FIG. 94, as the piston member 660 descends, the button part 664 contacts the top of the housing body 621, and the first spring 665 is compressed.

Therefore, the power supply part 670 and the connection terminal 661 b are connected through the button part 664.

Furthermore, as the piston member 660 further descends, the bottom of the piston part 661 joins the top of the intermediate plate 626, and simultaneously, the connection terminal 661 b contacts the connection terminal 626 a.

Accordingly, the power supply part 670 and the first heating wire 630 are connected by the connection terminal 661 b and the connection terminal 626 a, and thus, the first heating wire 630 is heated.

In this case, when the button part 664 is slightly pushed, the connection terminal 661 b and the connection terminal 626 a are not connected, but, when the button part 664 is sufficiently pushed, the connection terminal 661 b and the connection terminal 626 a are connected. Therefore, when the piston member 660 ascends and descends, the first heating wire 630 is not unnecessarily heated.

Furthermore, as the piston member 660 further descends, the bottom of the piston part 661 downwardly presses the top of the intermediate plate 626, and thus, the elastic part 625 is pressed and compressed in a downward direction, thereby dropping the pressurization part 623.

As the pressurization part 623 descends, the first heating wire 630 is connected to and heated by the power supply part 670, and the heated first heating wire 630 also descends. Therefore, the first heating wire 630 strongly presses the top of the vinyl bag 690.

As described above, as the heated first heating wire 630 strongly presses the top of the vinyl bag 690, by heating the first heating wire 630, as illustrated in FIG. 95, a heat suture portion 694 is formed around the cut portion 695 of the vinyl bag 690 cut by the punch projection 629.

At this point, since the first heating wire 630 is disposed to surround the punch projection 629, the cut portion 695 of the vinyl bag 690 is blocked from the inside of the vinyl bag 690 by the heat suture portion 694.

Furthermore, as illustrated in FIG. 95, the heat suture portion 694 is connected to the side junction portion 692 of the vinyl bag 690 by the first heating wire 630.

After the vacuum applying and heat suturing of the vinyl bag 690 are completed, the user removes a force that is downwardly applied to the piston member 660.

Then, the button part 664 upwardly pushes up the piston member 660 by the springback force of the first spring 665.

Therefore, the connection terminal 626 a and the connection terminal 661 b are blocked from each other.

The pressurization part 623 is lifted by the springback force of the compressed elastic part 625, and thus, the first heating wire 630 is separated from the vinyl bag 690.

When intending to apply vacuum into a separate vacuum vessel (not shown) or separate a cork from a wine bottle (not shown), the first connection hole 612 a formed in the receiving part 612 is opened using the connection door 612 b, the first connection hole 612 a is disposed on the vacuum vessel or the cork of the wine bottle, and the internal air of the vacuum vessel is discharged to the outside through the inside of the housing 620 by reciprocating the piston member 660, thereby applying vacuum into the vacuum vessel or separating the cork from the wine bottle.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
